interface documentation

An _IGroupExchangeKexAlgorithm describes a key exchange algorithm that uses group exchange between the client and server.

A prime / generator group should be chosen at run time based on the requested size. See RFC 4419.

Inherited from _IKexAlgorithm:

Attribute hashProcessor A callable hash algorithm constructor (e.g. hashlib.sha256) suitable for use with this key exchange algorithm.
Attribute preference An int giving the preference of the algorithm when negotiating key exchange. Algorithms with lower precedence values are more preferred.
