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

MAP: The mapping of SSH hmac algorithms to their implementations

Public Class Methods

get(name, key="", parameters = {}) click to toggle source

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

# File lib/net/ssh/transport/hmac.rb, line 37
def self.get(name, key="", parameters = {})
  impl = MAP[name] or raise ArgumentError, "hmac not found: #{name.inspect}"
  impl.new(Net::SSH::Transport::KeyExpander.expand_key(impl.key_length, key, parameters))
end

key_length(name) click to toggle source

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

# File lib/net/ssh/transport/hmac.rb, line 43
def self.key_length(name)
  impl = MAP[name] or raise ArgumentError, "hmac not found: #{name.inspect}"
  impl.key_length
end
