# Net::SSH::Test::Kex

An implementation of a key-exchange strategy specifically for unit tests. (This strategy would never really work against a real SSH server--it makes too many assumptions about the server's response.)

This registers itself with the transport key-exchange system as the "test" algorithm.

### Public Class Methods

new(algorithms, connection, data) click to toggle source

Creates a new instance of the testing key-exchange algorithm with the given arguments.

    # File lib/net/ssh/test/kex.rb, line 21
    def initialize(algorithms, connection, data)
      @connection = connection
    end

### Public Instance Methods

exchange_keys() click to toggle source

Exchange keys with the server. This returns a hash of constant values, and does not actually exchange keys.

    # File lib/net/ssh/test/kex.rb, line 27
    def exchange_keys
      result = Net::SSH::Buffer.from(:byte, NEWKEYS)
      @connection.send_message(result)

      buffer = @connection.next_message
      raise Net::SSH::Exception, "expected NEWKEYS" unless buffer.type == NEWKEYS

      { :session_id        => "abc-xyz",
        :server_key        => OpenSSL::PKey::RSA.new(512),
        :shared_secret     => OpenSSL::BN.new("1234567890", 10),
        :hashing_algorithm => OpenSSL::Digest::SHA1 }
    end
