Class Method Summary collapse
-
.get(name, key = "", parameters = {}) ⇒ Object
Retrieves a new hmac instance of the given SSH type (
name
). -
.key_length(name) ⇒ Object
Retrieves the key length for the hmac of the given SSH type (
name
).
Class Method Details
.get(name, key = "", parameters = {}) ⇒ Object
Retrieves a new hmac instance of the given SSH type (name
). If key
is given, the new instance will be initialized with that key.
