Handshake failure on some urls

[divadres]

Hello,
When I try to open some web I receive a 'handshake_failure' why can it be ?? An example is https://yape.nu, but there are more

  File "C:\Python27\lib\site-packages\tlslite\utils\deprecations.py", line 34, in wrapper
    return func(*args, **kwargs)
  File "C:\Python27\lib\site-packages\tlslite\tlsconnection.py", line 373, in handshakeClientCert
    for result in handshaker:
  File "C:\Python27\lib\site-packages\tlslite\tlsconnection.py", line 391, in _handshakeClientAsync
    for result in self._handshakeWrapperAsync(handshaker, checker):
  File "C:\Python27\lib\site-packages\tlslite\tlsconnection.py", line 2226, in _handshakeWrapperAsync
    for result in handshaker:
  File "C:\Python27\lib\site-packages\tlslite\tlsconnection.py", line 492, in _handshakeClientAsyncHelper
    for result in self._clientGetServerHello(settings, clientHello):
  File "C:\Python27\lib\site-packages\tlslite\tlsconnection.py", line 711, in _clientGetServerHello
    HandshakeType.server_hello):
  File "C:\Python27\lib\site-packages\tlslite\tlsrecordlayer.py", line 707, in _getMsg
    raise TLSRemoteAlert(alert)
tlslite.errors.TLSRemoteAlert: handshake_failure

The server does not have RSA certificates installed, only ECDSA:

so when we advertise that we don't support ECDSA, it's the server (the "remote" part of TLSRemoteAlert) that rejects the connection as being unable to negotiate a shared set of algorithms (handshake_failure)

It's a known limitation: #52

There's a beginning of an implementation: #196, but nobody is actively working on it.
