Class Method Details

.get(name, key = "") ⇒ 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.

def self.get(name, key="")
  impl = MAP[name] or raise ArgumentError, "hmac not found: #{name.inspect}"
  impl.new(key)
end

.key_length(name) ⇒ Object
