![]() Versions of John prior to 1.8.0 displayed only the C/s rate (calling it c/s).įinally, John the Ripper has gained the "-fork=N" and "-node=MIN/TOTAL" options for trivial parallel and distributed processing. ![]() The four speed metrics are as follows: g/s is successful guesses per second (so it'll stay at 0 until at least one password is cracked), p/s is candidate passwords tested per second, c/s is "crypts" (password hash or cipher computations) per second, and C/s is combinations of candidate password and target hash per second. Now it includes as many as four distinct speed metrics. I'd like to thank magnum and bartavelle for running additional tests, which first helped spot a problem and then confirmed that, after my fix, the new incremental mode consistently outperformed the old one in their tests as well.Īnother thing that changed is the status line. As an exception, digits.chr contains data for lengths of up to 20. Now default builds are capable of lengths of up to 24 and of the full 8-bit character set (except only for the NUL character), although most of the supplied charset files only contain data for lengths of up to 13 (this is not an arbitrary choice, but is a reasonable cut-off based on our testing). Also, incremental mode's length and character set limitations in default builds have been lifted. Meanwhile, magnum is regularly sync'ing the bleeding-jumbo branch on GitHub to be based on the latest core tree (which means 1.8.0 at the moment).Īs planned, John the Ripper 1.8 features a new revision of incremental mode with better efficiency in terms of passwords cracked per candidate passwords tested. chr files are available at this time (to be used mostly on Unix-like systems, where building from source is customary and convenient), we do intend to release Windows build(s) of JtR 1.8.x, a jumbo based on 1.8.x, and a Pro based on 1.8.x at a later time. ![]() ![]() ) (Seriously, though, I'd be happy to have released both 1.7 and 1.8 much sooner.)Īlthough only JtR 1.8.0 source code and. Curiously, it's also been a little over 7 years between versions 1.6 (late 1998) and 1.7, so it was time for a 1.8. This version number reflects that we view this as a major release, considering that version 1.7 came out in early 2006 - more than 7 years ago - and there have been only (many) minor releases during those years (the latest of them being 1.7.9). Concluding phase one of the Magnificent7 project, I've released John the Ripper 1.8.0 today. ![]()
