The ESP32 supports several different wireless communication protocols. Each protocol has its advantages and disadvantages and one can be more suitable than the other depending on the application. This guide is a compilation of all our articles about wireless communication protocols with the ESP32.
In this article, we’ll cover the following communication protocols:
We’ll keep this article updated as new tutorials are posted.
Bluetooth Low Energy (BLE)
Bluetooth Low Energy, BLE for short, is a power-conserving variant of Bluetooth. BLE’s primary application is short-distance transmission of small amounts of data (low bandwidth).
Unlike Bluetooth which is always on, BLE remains in sleep mode constantly except for when a connection is initiated. This makes it consume very low power. BLE consumes approximately 100x less power than Bluetooth (depending on the use case).
Additionally, BLE supports not only point-to-point communication, but also broadcast mode, and mesh network. Due to its properties, BLE is suitable for applications that need to exchange small amounts of data periodically running on a coin cell. For example, BLE is of great use in healthcare, fitness, tracking, beacons, security, and home automation industries.
- Low power consumption
- Short distance transmission
- Low bandwidth (small amounts of data)
- Ideal for exchanging small amounts of data periodically
- Supports point-to-point, broadcast, and mesh network
Learn how to get started with BLE on the ESP32 with our guides:
- Getting Started with ESP32 Bluetooth Low Energy (BLE) on Arduino IDE
- ESP32 BLE Server and Client (Bluetooth Low Energy)
Bluetooth is a wireless technology standard used for exchanging data between fixed and mobile devices over short distances. It is optimized for continuous data streaming, while BLE is optimized for short burst data transmission. It consumes approximately x100 more power than BLE.
- Short distance transmission
- Optimized for continuous data streaming
Learn how to use Bluetooth Classic with the ESP32:
ESP-NOW is a connectionless communication protocol developed by Espressif that features short packet transmission. This protocol enables multiple devices to talk to each other in an easy way.
Stating the Espressif website, ESP-NOW is a “protocol developed by Espressif, which enables multiple devices to communicate with one another without using Wi-Fi. The protocol is similar to the low-power 2.4GHz wireless connectivity (…). The pairing between devices is needed prior to their communication. After the pairing is done, the connection is safe and peer-to-peer, with no handshake being required.”
- Fast communication protocol
- Up to 250-byte payload can be carried
- Encrypted and unencrypted communication
- Range communication (220 meters in opan en field accordingly to our experiments)

Wi-Fi (client-server communication protocols)
You can exchange data between ESP32 boards using HTTP requests. One board acts as a server (Wi-Fi access point) and the other board acts as a client (Wi-Fi station).
Learn how to send data from one ESP32 board to the other using HTTP requests:
The ESP32 can also make HTTP requests to third-party services on the internet to send or receive data. For that, the ESP32 needs to be connected to a Wi-Fi network with internet access.
Server-Sent Events (SSE) allow the client to receive automatic updates from a server via HTTP connection.
The client initiates the SSE connection and the server uses the event source protocol to send updates to the client. The client will receive updates from the server, but it can’t send any data to the server after the initial handshake.
Server-sent events are useful when you need to send new data to the server without the need for a request by the server, for example send sensor readings periodically or notifications.
Learn how to use server-sent events on an ESP32 web server:
A WebSocket is a persistent connection between a client and server that allows bidirectional communication between both parties using a TCP connection. This means you can send data from the client to the server and from the server to the client at any given time.
Get started with WebSocket protocol on the ESP32 by following the next tutorial:
MQTT stands for Message Queuing Telemetry Transport. It is a lightweight publish and subscribe system where you can publish and receive messages as a client. MQTT is a simple messaging protocol, designed for constrained devices with low-bandwidth.
To use MQTT to exchange data, you need an MQTT broker that is responsible for receiving all messages, filtering the messages, and publishing the message to all subscribed clients. MQTT is perfect for IoT projects with multiple devices.
Read our articles about the MQTT communication protocol with the ESP32.

LoRa is a wireless data communication technology that uses a radio modulation technique that can be generated by Semtech LoRa transceiver chips.
LoRa allows long range communication of small amounts of data (which means a low bandwidth), and high immunity to interference while minimizing power consumption. So, it allows long distance communication with low power requirements.
- Long range communication
- Low bandwidth (small amounts of data)
- High immunity to interference
- Low power consumption
To use LoRa with the ESP32 boards, you need a LoRa transceiver chip. The word “transceiver” means that the chip can send and receive LoRa messages. There are ESP32 boards that already come with an on-board LoRa transceiver chip, which makes wiring much simpler.
Read our articles about LoRa communication:
- ESP32 with LoRa using Arduino IDE – Getting Started – learn what is LoRa, how to connect a LoRa chip to the ESP32, and exchange data between boards.

- ESP32 LoRa Sensor Monitoring with Web Server (Long Range Communication) – set up an ESP32 as a LoRa receiver and as a web server to display received readings.
You can connect your ESP32 board to a modem to be able to send and receive SMS and phone calls and connect to the internet using a SIM card as you would do with your smartphone. Some of those modems can also get GPS data like latitude, longitude, altitude, and date and time.
There are different modules available that are compatible with the ESP32 and there are also ESP32 boards that already come with a built-in modem and all the necessary circuitry.
We’ve experimented with the ESP32 SIM8000L (2G), and the ESP32 SIM7000G (3G and 4G), and we had pretty good results.
To get started with those boards, you can take a look at the following tutorials:
- Getting Started with LILYGO T-SIM7000G ESP32 (LTE, GPRS, and GPS)
- ESP32 Publish Data to Cloud without Wi-Fi (TTGO T-Call ESP32 SIM800L)
- ESP32 SIM800L: Send Text Messages (SMS Alert) with Sensor Readings
- Connect ESP32 to Cloud MQTT Broker (TTGO T-Call ESP32 SIM800L)
There are many different wireless communication protocols compatible with the ESP32 boards. This makes it one of the most versatile boards for IoT and Home Automation projects. In this article, we’ve covered LoRa, Bluetooth, Bluetooth Low Energy, ESP-NOW, Wi-Fi, MQTT, and GSM/GPRS/LTE.

WWOWOWOWOWOWOW! Great article. Its wonderful to see a complete and comprehensive post about the communication capabilities of the ESP32!
Thank you for this nice article, again 😉
I was wondering about how you can have secure/encrypted communication over these protocols? Do you have links/insights on this topic related to ESP32?
Are you considering an article about such topic?
Would be much appriciated!
About ESP-NOW encrypted messages: https://randomnerdtutorials.com/esp32-esp-now-encrypted-messages/
For WiFi, you can use WiFiClient secure: https://github.com/espressif/arduino-esp32/blob/master/libraries/WiFiClientSecure/examples/WiFiClientSecure/WiFiClientSecure.ino
At the moment, we don’t have any in-depth tutorials about these subjects.
I’ll write something about it in the future.
Hi. This is very useful, as most of the stuff you publish is.
Thank you very much for your constant research and support.
A great and useful overview. Thank you!
Excellent article. Really one of the first decisions you need to make with any ESP32 is what protocol to use. Keep up the good work.
No mention of the NRF24, good range, up to 2mb speed and reasonable packet size?
Rui, Sara, You are THE BEST!
Very much appreciate your tutorials and articles, and your response to emails!!
And love your eBooks!
Have greatly benefitted from your contributions in this space!
Thank you so much for your nice words!
I’m questioning the ESPNow portion of this article. In my experience, pairing is not required, only address. Additionally by default it is not secure or encrypted.
One thing I’m very curious about is Long Range mode for ESP32. There is not much documentation or examples utilizing it. I’m curious if it’s just using the antenna at a higher DBI.
Sarah and Rui = one-click help:)
If you read carefully what they write and then work consistently, 99.9% of the time everything works – one-tenth is because no person is infallible – my experience so far. And a lot of their work is just for thanking you here, so warm thanks.
On the topic: my esp 8266 is updated via wifi and OTA, esp32 should also be done.
Hi, thanks for the great job.
I have a question about ESM32CAM client stream on TTGO server, that is must power on server first, and power on client next, any way to improve this please?
Thanks for the article. Unfortunately, most of the Maker Advisor links for LoRa boards are expired. You may not be benefitting from any referrals there also. I am a little cautious in searching for my own items, as there are so many variations and not all of them might work. Perhaps you could have a look into this ?
Best regards – Noel
Thanks for the warning. I’ll try to update the page today.
I updated the Maker Advisor page.
Basically, these boards are deprecated. You can only find them on Banggood, Aliexpress or eBay.
On Amazon, you can find the most recent and improved version 2.1. I haven’t tried the 2.1 version, but it should work similarly, with enhanced features and better range.


Should a fire or emergency ever occur in your building, you don’t want first responders to lose communications due to a dead spot.
Unfortunately, dead spots are an all too common occurrence in buildings of all sizes, heights, and ages. However, monumental shifts are happening in building safety and compliance to address the widespread issue of dead spots. Bi-Directional Amplifier (BDA) systems are becoming more prevalent in multi-story buildings across the United States.
Though not yet mandated for all properties in Alabama, Bi-Directional Amplifier (BDA) systems are becoming more commonplace in both new and older buildings alike. With that said, companies and building owners throughout Alabama should start considering the benefits of BDAs and when to install them.
Do you own a multi-story commercial building, or are you starting a new multi-story construction project in the Birmingham, AL, area? Let Prestige Alarm be your partner in securing and enhancing your building’s crucial communication coverage and emergency response system.
If it’s time to take your security to the next level, read on to discover more about Bi-Directional Amplifiers, or contact us today to schedule a free consultation.
What is a BDA?
Dead spots occur when radio frequency signals cannot penetrate concrete, metal, underground structures, thick building materials, and other barriers. They can cause flat signal strength, spotty and inconsistent radio coverage, and interfere with first responders and their ability to communicate with one another.
A BDA is a two-way amplifier that transmits and receives radio frequency signals back and forth from a local wireless tower, and also works in unison with a Distributed Antenna System (DAS) within a building. As they simultaneously extend coverage range, a BDA and DAS amplify radio frequency signals and rebroadcast them throughout a building, including underground areas, stairwells, parking garages, and other problematic areas where dead spots occur.
Are BDAs Federally Mandated?
There are no federal requirements for BDA systems. Municipalities determine their own fire codes and safety guidelines for buildings within their jurisdictions, based on standards set by organizations like the National Fire Protection Agency (NFPA), the International Fire Code (IFC), the International Code Council (ICC), and others.
As per new standards established in Section 510 of the 2018 International Fire Code by the IFC, any newly constructed building must provide ample radio coverage ‒ within the building ‒ for emergency responders. This approved radio coverage must be “based on the existing coverage levels of the public safety communication systems utilized by the jurisdiction.”
The IFC sets the minimum standard for fire prevention and in-building signal coverage laws ‒ but requiring BDA systems for buildings is ultimately up to local jurisdictions and the discretion of local fire marshals and departments.
Are BDAs Required in Alabama?
In Alabama, BDA systems are required for all new construction, remodeling, and addition projects, but not yet mandatory for all properties.
Generally speaking, most jurisdictions require newly constructed and/or multi-story buildings to have Bi-Directional Amplifiers. They are most commonly mandated in places like military bases, hospital zones, shopping complexes, sports arenas, school campuses, prisons, condominiums, resorts, and hotels.
Soon, mandated radio communication coverage will extend to all properties across Alabama, regardless of property age, size, or height. So the issue of installing BDAs is not a matter of if, but when.
What Are the Requirements for a BDA System?
It is the responsibility of building owners to cover the costs of installing and maintaining BDA systems. Certified professionals must design and install BDA systems and meet rigorous standards set in place by both the Authority Having Jurisdiction (AHJ), the Federal Communications Commission (FCC), and various other fire prevention and protection organizations.
Prestige Alarm is a local authorized dealer, installer, and certifier of Honeywell Bi-Directional Amplifiers. These industry-leading, state-of-the-art BDA systems are designed to exceed code compliance requirements, and we’ll ensure your BDA is retrofitted to your exact building specifications and radio coverage needs.
What Occurs During the Installation Process?
During the installation process, we’ll first design an architectural plan for your unique building that identifies dead spots, critical areas, and addresses the materials used to construct your building. One of our licensed electricians will then install the BDA, along with a signal-boosting antenna that can receive communications from the local radio tower. We’ll ensure your BDA system has an adequate electrical connection, back-up power, and airflow for maximum efficiency and performance.
Once the installation process is complete, we’ll test the BDA system, certify its signal coverage, and submit it to the AHJ.
Take Your Building’s Safety to the Next Level
Are you ready to install a Bi-Directional Amplifier for your multi-story building or commercial property?

• Ultrasonic exposure + voice imitation = 100% jamming • 5 ultrasonic transducers and powerful speaker • Absolutely soundless operation possible • Suppression range up to 7 m (23 ft), super effective - 2 m (7 ft) • Very powerful emission - up to 120 dB • External speakers plug in capability for big rooms • Detailed English manual included
The device is designed to protect conversation areas from eavesdropping. Device blocks wireless microphones, tape recorders, hard-wired microphones and most of professional digital voice recorders including recorders installed in mobile phones (smartphones). Ultrasonic inaudible noise signal, as well as acoustic speech-like noise signal, are used in jamming the eavesdropping devices.
The device should be placed directing transducers towards possible location of eavesdropping devices (tape and digital recorders, microphones, "bugs" etc.), for example, toward the new visitors or clients. The optimal distance from transducers to microphone of the eavesdropping device is up to 2 meters (7 feet). Then switch ON the device and adjust the volume of the acoustic speech-like signal so that you can still hear the person you are talking to. You should hold conversation in a low voice but so that you hear each other well without repeating every word. Use TURBO mode for more effective jamming of the microphones.
Do not switch on the acoustic speech-like signal when you want the device to be hidden. Note that this would somewhat reduce the effectiveness of the device (the manufacturer cannot guarantee that if you use ultrasonic signal only the device would jam all voice recorders).
It is recommended to connect the device to external speakers (e.g. computer) through the special jack in order to expose the acoustic speech-like signal in a large room more effectively. This will protect the large conversation area from eavesdropping as well as eliminate the chance of eavesdropping by external directed microphones (such as laser).
Package contents: - Microphone, bug and voice recorder suppresor "BugHunter DAudio bda-2 Voices" with five Ultrasonic transducers and acoustic silencer. - External power supply adapter (battery charger) 220 V, 50 Hz,
- Individual package - User Manual in English - Quality checklist

Weekly Hours: 4
ECTS Credits: 7
Course Homepage: http://www.cs.uoi.gr/~tsiatouhas/Y2-RIS.htm
Description: With the continuous scaling of transistor feature size, the chip complexity is dramatically increased since billions of transistors are integrated in a single chip (see the case of Systems-on-Chip – SoCs). Aiming to provide high quality integrated circuits and systems, these must be reliable and fully tested after production. In addition, during their whole operational life time in the field, we must ensure their reliable and uninterruptable operation. Consequently, design for reliability is an integral part of integrated circuits and systems design and manufacturing. This course covers the fields of integrated circuits and systems testing, design for testability and design for reliability. The topics discussed are: Importance of testing, Defects and fault models, Wear out and aging mechanisms, PVT variations, Test process, Advanced design for testability techniques, Advanced design for reliability techniques, Self-healing systems.


PSCC to Certify TDMA for Voice Only Following Interference Reports
After nearly three months of research, the Public Safety Communications Council (PSCC) advised the FCC that the public-safety certified frequency advisory committees will certify TDMA coordinations only for voice emissions because of interference reports in VHF spectrum.
“The issues we are receiving reports on can be caused by many things, one of which is the data carried on the radios,” said William Brownlow, telecommunications Manager for American Association of State Highway and Transportation Officials (AASHTO). “The GPS and AVL type of information is supposed to be secondary but because it’s superimposed on the voice stream, you can’t separate the two of them. It’s the loading of the channel with all the data that’s one cause of the interference being reported. So until we can figure out how to separate the data and voice, we can’t certify the system coordination except for voice at present.”
The coordinators will also only certify TDMA coordinations at power levels that are 3 dB or more below the currently licensed analog effective radiated power (ERP), or at least 3 dB or more below the values indicated in 90.205, the safe harbor tables.
The interference is affecting only Digital Mobile Radio (DMR) deployments in VHF frequencies between 150 and 174 MHz, said Brownlow. “It’s only noticed in the VHF frequencies because they aren’t paired,” he said. “Some of the interference has been reported from stations 140 kilometers apart.”
The PSCC said in February it received reports of harmful interference from users around the country from TDMA systems. One instance was a channel successfully shared when the use averaged around 10 percent and now approaches or is at a 100 percent duty cycle. Another source of interference is false triggering of certain continuous tone-coded squelch system (CTCSS) tones in analog receivers, presumably by harmonics of the TDMA framing rate, which fall on or close to CTCSS frequencies, opening receivers and causing constant noise in affected channels. The February letter from PSCC to the FCC is available here.
Monique Princen, chair of the DMR Association marketing working group, said the association is aware of the reports. “Based on our member’s know-how and experience with customers using DMR and analog equipment on shared frequencies worldwide, both the reduced available duty cycle for analog users in shared systems as well as false CTCSS triggering issues can be prevented,” Princen said.
She said the reported instances of false CTCSS triggering are extremely low. “Users looking to migrate to digital and to share a channel with analogue terminals should have few concerns regarding this issue but should discuss it with their supplier to determine if there exists the need to conduct tests to detect any problem.”
The PSCC, a consortium of the four public-safety frequency advisory committees, also recommended that a limitation be placed on licenses, advising affected operators that only voice operations and incidental signaling, such as embedded unit identification and emergency status indication, which do not appreciably extend channel occupancy, are allowed. In February, PSCC agreed to limit VHF TDMA systems to a maximum 10 watts ERP.
The FCC hasn’t yet responded to the PSCC initiative. PSCC also asked the Telecommunications Industry Association (TIA) to conduct testing of all available TDMA hardware operating in the VHF band to assess their impact on existing equipment. TIA hasn’t provided a formal response, Brownlow said.
PSCC is composed of AASHTO, Association of Public-Safety Communications Officials (APCO) International, the Forestry Conservation Communications Association (FCCA) and the International Municipal Signal Association (IMSA).

I though of another option for you to use USB with a Mimby. With my Bimby I use a NAD DAC 2. It has a little transmitter that plugs into your computer's usb then sends the digital signal up to 24 bit 96hz to a little box that sits next to the Bimby. The little box sends a digital signal by coax into the Bimby. To me it sounds just as good as when I was using the coax output of my FiiO X5 into the Bimby. And having the wireless is very nice. It does not use your network wifi. It has 3 frequencies to choose from and you just match the box and transmitter. Was supper easy to set up. Just plugged it in and it worked. Keep in mind I do not use the internal DAC of the NAD DAC2. I just use it to pass the digital signal from my computer usb to my Bimby using the Bimby's coax input. Here are some links: https://nadelectronics.com/product/dac-2/ Note that this review convinced me to get it because of this quote: "One interesting caveat to this is switching from using the NAD via the analogue outputs to the coaxial one into another DAC shows that it is a completely transparent wireless transfer device. With the NAD running into the digital input of a Naim ND5 XS, the performance is completely in keeping with the performance of the more expensive streamer and transfer at sampling rates up to 24/96kHz is seamless and extremely effective." https://www.avforums.com/review/nad-dac2-wireless-dac-review.10052 I ordered mine off Amazon.


- DBUS interface including a new communication protocol
- ConsoleKit integration
- Separate compilation and distribution of modules
- Simplified configuration so that users do not need to change it
1. DBUS interface
We will first make a brief analysis of what needs to be done for proper session integration with ConsoleKit and DBUS communication. The new DBUS interface will offer the same functionality as SSIP but should already be designed in a way that it can be later extended to the new high level API based on TTS API and being able to support additional requirements we have on the API on top of what SSIP already supports. Thus we will first need to develop the specification for it and then implement it.
2. Modules auto-load
The AddModule configuration option will be removed and available modules (based on presence of a binary providing the correct interface in a given location) will be loaded automatically.

The Best Kind of Long-Distance Relationship.
Your clinicians can’t assess their patient’s recovery with dialogue alone. They need to be able to see the patients to get an accurate read on them. However it can be inconvenient, and at times even impossible to schedule routine check-up meetings.
Who would have thought that your EMR software could provide the solution? The Alleva Mobile app comes equipped with a HIPAA secure video conferencing feature. In contrast to simply using Skype or FaceTime to connect to a patient, the Alleva App’s video conferencing feature is in accordance with all of HIPAA’s regulations. Now clinicians can connect face-to-face with their patients from anywhere at anytime.


Telemedicine may be as simple as two health professionals discussing a case over the telephone, or as complex as using satellite technology and video-conferencing equipment to conduct a real-time consultation between medical specialists in two different countries. Telemedicine generally refers to the use of communications and information technologies for the delivery of clinical care.
Telemedicine is a rapidly developing application of clinical medicine where medical information is transferred via telephone, the Internet or other networks for the purpose of consulting, and remote medical procedures or examinations.

After a period of speculation, Huawei 5G equipment is officially banned from UK telecoms networks and must be removed by 2027.
The U-turn decision was made by UK Prime Minister, Boris Johnson, after intense pressure from the US stating that using Huawei’s 5G equipment is a threat to national security as it relies on non-US components. Initially, UK government decided back in January to allow Huawei to supply 35% of the UK’s 5G equipment but capped it’s market share. But now it must be removed entirely. In addition, it will be illegal in the UK to buy new Huawei 5G equipment after 31 December 2020.
Current Huawei users include the likes of BT, whose EE mobile network features Huawei within its 4G and 5G hardware. However BT has vowed that it will remove Huawei from its 5G network and replace it with Ericsson’s products in the next three years. It’s currently unclear if similar deadlines will be put in place for other Huawei equipment.
Regardless of the suspicion surrounding Huawei, the company denies all allegations of espionage. A spokesperson for the business has warned that pushing them out of UK networks will lead Britain into the digital slow lane, and could prove to be an expensive decision. Though we don’t know exactly how networks will cope after scrapping Huawei, experts have said that it is likely to delay the full fibre rollout in the UK by more than two years and could push up costs by up to £2 billion.
Is older generation Huawei kit still allowed?
Huawei has been operating in the UK for more than 20 years and played a huge role in the rollout of 2G, 3G and 4G networks. Therefore, despite the ban on 5G equipment, older generation kit (2G, 3G and 4G) can stay until they are no longer needed. The older kit is not believed to be a threat as it’s easier to monitor.
With older generation Huawei equipment here to stay for now, questions arise around the impact of availability on critical spares. From experience, we can forecast operators emergency stockpiling Huawei spares before stocks become sparce.
We recommend partnering with a reliable telecom network partner who is experienced in sourcing equipment to help you maintain your Huawei networks when supply and demand of equipment spikes. Here at TXO we stock over 800,000 parts in our global warehouses including lots of Huawei kit. In addition to our current stock we have a network of reliable partners worldwide that help us to source new and refurbished telecom network equipment with ease.
Do you have Huawei equipment affected by the ban?
We understand that operators may have already invested in Huawei 5G equipment, but this doesn’t have to be the end of its useful life. Of course, there will still be a demand for Huawei kit in other countries without a ban on the manufacturer. Therefore, we can deinstall, collect and sell your equipment to other clients where the kit is needed. Excess inventory can take up space in your warehouses and ties up cash, so we want to support you.
As a telecom equipment reseller, we want to buy your surplus networking equipment so you can turn unneeded inventory into cash or credit via our two purchasing models: outright purchase and consignment. Whether it’s new, used, out-of-warranty, discontinued, obsolete or decommissioned – we will buy your surplus routers, switches, servers, line cards and other types of mobile and fixed line equipment and give you a fair market evaluation of its worth so that you can achieve maximum ROI.
The Huawei ban does not mean that kit should be disposed of. Here at TXO, supporting the Circular Economy has been part of our vision since the very beginning. We believe that the decision to ban Huawei 5G equipment should not add towards the global e-waste problem. Steps should be taken to support the Circular Economy, whether this be through resale, reuse or recycling. For further information on how you can meet CSR and sustainability goals, check out our page on TXO & the circular economy.
If your network is affected by the Huawei 5G ban, we’re here to help. Contact a member of our team to discuss your next steps.

Encryption is performed to ensure the safety and privacy of information sent from one party to another. “Keys” are used to lock (encrypt) and unlock (decrypt) the data that’s transmitted, and if a single key is used for this purpose then symmetric encryption is said to have occurred. This method only works when the key that’s used is kept absolutely secure, and as a secret between the two communicating parties.
But for most practical applications, several parties or communication transactions may be involved, and it becomes necessary for encryption keys to be transmitted over networks whose security may be in doubt. That’s where asymmetric encryption comes into the picture.
Here, a pair of keys is used to encrypt or decrypt communications. There’s a private key, held separately by its owner, and a public key which can be visible to everyone, and distributed to intended recipients. Messages are encrypted with the public key, then decrypted by the holder’s unique private key – which may also be used in creating digital signatures.
Public Key Infrastructure (PKI) uses a combination of asymmetric and symmetric processes. An initial “handshake” between communicating parties uses asymmetric encryption to protect the secret key which is exchanged to enable symmetric encryption. Asymmetric encryption is used for the rest of the communication, once the secret key has been exchanged.
