Can code in the Heimdal distribution be used to decode a pre authentication using the RC4-HMAC encryption type used by Windows 2000? If so, can you give me a short road map to the code? I am thinking that the testrc4.c program can be modified for this purpose, but I wanted to ask before I go too far down this path. Thanks.
