Implements a simple factory interface for fetching hmac implementations, or for finding the key lengths for hmac implementations.s
The mapping of SSH hmac algorithms to their implementations
Retrieves a new hmac instance of the given SSH
type (name
). If key
is given, the new instance
will be initialized with that key.

Retrieves the key length for the hmac of the given SSH type (name
).
