It implements only - the minimum necessary for SMB authentication, as used by all SMB - products (including every copy of Microsoft Windows95 ever sold) - - In particular, it can only do a unchained forward DES pass. This - means it is not possible to use this code for encryption/decryption - of data, instead it is only useful as a "hash" algorithm. - - There is no entry point into this code that allows normal DES operation. - - I believe this means that this code does not come under ITAR - regulations but this is NOT a legal opinion.
