Post: RE: Cracking SHA1(linkedin)

Actually the situation is a bit worse. hashcat only checks the last 16 bytes of the sha1 hash $ echo -n 'testing123' | sha1sum 4c0d2b951ffabd6f9a10489dc40fc356ec1d26d5 *- $ hashcat -m 100 -a3 -...

Yes the odds of that happening are 1 in (2^(160-20 bits)) = 1/2^140 ~ 1 in 1.39e42 Yet it seems someone may have discovered such a collision: source: https://www.win.tue.nl/~aeb/linux/john/jo...

Post: RE: Cracking SHA1(linkedin)

It seems like hashcat v6.1.1 is still using the masked hash logic for SHA1 (-m 100 ) which should probably be marked as bug. That is to say that hashcat seems to be ignoring the first 5 nibbles of the...

Getting some interesting results for NETNTLMv1 ... It would seem hashcat with dictionary and rules is much faster then oclhashcat (brute or dic+rules) for large number of hashes. Also using hashcat wi...
