On this line: https://github.com/twisted/twisted/blob/trunk/src/twisted/conch/ssh/keys.py#L782 the __repr__() function wants to call the key_size() method. This seems to exist for DSA and RSA keys: https://github.com/pyca/cryptography/blob/master/src/cryptography/hazmat/backends/openssl/dsa.py#L232 https://github.com/pyca/cryptography/blob/master/src/cryptography/hazmat/backends/openssl/rsa.py#L482 However for EC keys, I do not see a 'key_size' attribute: https://github.com/pyca/cryptography/blob/master/src/cryptography/hazmat/backends/openssl/ec.py#L256 When trying to compare the known host key, the code tries to do a __repr__() and it fails, so this doesn't seem to work with EC keys. -- Craig
