I remember adding it because i started writing a PSK cracker, and I wanted to test the HMAC functions. But devine just wrote his own in aircrack, and I never bothered with this again. (BTW, the implementation in aircrack-ng is not so good, especially on AMD64) Is there a single application that uses just a call to HMAC-MD5? I never seen any question about its usage here. It might be a good idea to just dump it ... -- To unsubscribe, e-mail john-users-unsubscribe@...ts.openwall.com and reply to the automated confirmation request that will be sent to you.
