module Net::SSH::Transport::HMAC
Implements a simple factory interface for fetching hmac implementations, or for finding the key lengths for hmac implementations.s
Constants

Retrieves a new hmac instance of the given SSH
type (name
). If key
is given, the new instance will be initialized with that key.
