Implementation of the the rest of NTLM authentications, tested against both Windows/ISA and Samba/Squid: full featured NTLMv2 with its new strong password hash and NTLM2 Session Response (NTLMv1.5) offering better network security than NTLM/LM in non-NTLMv2 environments. With these two new algorithms, Cntlm is THE ultimate auth proxy :) supporting every NTLM flavour invented. If you use Cntlm's autodetection, your password is probably better protected than it would be with native Windows.
