Please refer to <https://github.com/openwall/john/blob/bleeding-jumbo/doc/INSTALL-UBUNTU> instead. Here's how to make an optimal build of latest bleeding-edge code on Ubuntu Linux. Most of it applies to other distros too (also works for Ubuntu on Windows <https://msdn.microsoft.com/en-us/commandline/wsl/>). text/html 2012-11-06T01:14:50+02:00 https://openwall.info/wiki/john/tutorials/add-codepage?rev=1352160890&do=diff This is for developers, or other advanced users. So, you have a set of hashes, and they are in a code page for some language which John does not support. Well, john 'can' have code pages added to it's support. The code pages I know work, are 8 bit (256 character), and left to right reading direction. I do not know if other reading directions can be added. John does already have utf-8 support, but since this is a variable sized font/codepage, there are many things within john, which do not … text/html 2010-03-15T23:00:51+02:00 https://openwall.info/wiki/john/tutorials/macosx-salted-sha1?rev=1268690451&do=diff It is probably the simplest to use JtR Pro, which includes the XPWDUMP tool to dump the hashes and readily supports Mac OS X salted SHA-1 hashes. You can use the Mac OS X native or the Linux version of JtR Pro (in case you prefer to audit your OS X hashes on a Linux box) - both of them support these hashes (although the XPWDUMP tool is only included with JtR Pro for Mac OS X). text/html 2019-06-15T20:41:13+02:00 https://openwall.info/wiki/john/tutorials/remote-linux?rev=1560624073&do=diff The following instructions were originally written in response to a specific John the Ripper Pro support request. Retrieving all of your servers' password hashes for audits on a single system and automating this setup (presumably to repeat the audits on a regular basis) is not always the right thing to do. This poses a lot of extra risk to your servers' security. You could want to opt to deploy pam_passwdqc and do “manual” audits with JtR infrequently instead. On some systems, you may also s… text/html 2012-07-03T02:27:23+02:00 https://openwall.info/wiki/john/tutorials/sha-crypt?rev=1341275243&do=diff John the Ripper 1.7.6+ Detailed tutorials have been posted to the john-users list, separately for Linux (using Fedora 12 as the specific example) and for Solaris 10.
