Known implementations: twisted.conch.ssh._kex._DHGroupExchangeSHA1, twisted.conch.ssh._kex._DHGroupExchangeSHA256

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