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. ntlm-get-password-hashes NTLM authentication procedure example: 1.
