TLS does not work with RSA larger than 1024
I learned kind of the hard way, after some hours of troubleshooting that if you generate a certificate with a key size over 1024, p2pool will not work with it, it will start ok, but any connection is reset.
The error that shows  is:
`OpenSSL: error:0A000126:SSL routines::unexpected eof while reading`

The certificate that is generated by default with p2pool is  RSA:512, but 1024 also seems to work. Nothing more beyond that.

Is this something that can be improved in the future?
