This library is a direct translation of the Samba release 2.2.0 implementation of Windows NT and LanManager compatible password encryption.

Interface functions:

ntlm-build-auth-request
  This will return a binary string, which should be used in the
  base64 encoded form and it is the caller's responsibility to encode
  the returned string with base64.

ntlm-build-auth-response
  It is the caller's responsibility to pass a base64 decoded string
  (which will be a binary string) as the first argument and to
  encode the returned string with base64. The second argument user
  should be given in user@domain format.
