We can use the -lines=NUMBER parameter to split our file. SIZE may be (or may be an integer optionally followed by) one of following: version output version information and exit verbose print a diagnostic just before each l, -lines=NUMBER put NUMBER lines per output file d, -numeric-suffixes use numeric suffixes instead of alphabetic C, -line-bytes=SIZE put at most SIZE bytes of lines per output file b, -bytes=SIZE put SIZE bytes per output file a, -suffix-length=N use suffixes of length N (default 2) Mandatory arguments to long options are mandatory for short options too. Size is 1000 lines, and default PREFIX is `x'. Output fixed-size pieces of INPUT to PREFIXaa, PREFIXab. Under Linux we have a nice utility called split that does this job very well: split -help For that reason, we need to split this file. wc -l Īs you can assume, both John the Ripper and oclHashcat-plus are not able to load this file because it is too big. This file is 4.3 GB and includes 139444502 lines according to the wc utility. We will concentrate from now on the list. Longer_salts salted_with_md5 SHA1 vBulletin-v3.8.4 – New download! All in one sorted and cleaned version.įirst of all the KoreLogic torrent file file must be decompressed, it contains a folder named "hashes".– New example in the John the Ripper section: "Crack double MD5 hashes with the help of script".This article is about cracking the provided MD5 hashes of KoreLogic only, but the same strategy was also applied to the SHA1 hashes. The password cracking tools I used during this long trip were John the Ripper and oclHashcat-plus.
But I really wanted to give it a try because the field of password cracking fascinates me. This very big amount of password hashes at first discouraged me, as I only own a classic computer configuration with an AMD Phenom II 4 cores at 3,2 Mhz in addition to an ATI/AMD 5770 graphics card. It was several months ago, when I ( m3g9tr0n) saw a tweet from KoreLogic about a torrent file containing various hash lists of passwords for a total of 146 million passwords.
This is the story about how I cracked 122 million * password hashes with John the Ripper and oclHashcat-plus.
