Thread: md5(md5($pass).$salt)
Post: RE: md5(md5($pass).$salt)
| This is the algo used by vbulletin, see the --help output:
hashcat supports:
-m 2611 = vBulletin < v3.8.5
and
-m 2711 = vBulletin >= v3.8.5
the difference is mainly the supported salt length (s... |

Thread: Issue with --show and colon character
Post: RE: Issue with --show and colon character
| I think you indeed found the main root of the problem.
The potfile read/write functions should ignore the --outfile-autohex setting.

Thread: Issue with --show and colon character
Post: RE: Issue with --show and colon character
| hmm, this is an interesting case and the reason why it's behaving like this is that hashcat only checks for the last "separator" in the potfile, see: https://github.com/hashcat/hashcat/blob/067ffa9d64... |

Post: RE: help with hashing wpa2 gtx 1080 hashrate

what is your speed with hashcat -m 2500 -b ?
Are you sure you added the -w 3 parameter (or even -w 4) ? |
