| John the Ripper 1.7.6+ includes built-in parallelization for multi-CPU and/or multi-core systems by means of OpenMP directives. In 1.7.6, this was limited to [[http://www.openwall.com/crypt/|bcrypt]] hashes (with JtR's own optimized code) and SHA-crypt and SunMD5 hashes [[http://www.openwall.com/lists/john-users/2010/06/20/3|on recent Linux]] and [[http://www.openwall.com/lists/john-users/2010/06/20/2|Solaris]] systems (with system-provided thread-safe crypto code). All of this requires [[:internal/gcc-local-build|GCC 4.2 or newer]], or another OpenMP-capable C compiler (also tested with Sun Studio 12). To enable the OpenMP parallelization, the proper ''OMPFLAGS'' line in the ''Makefile'' needs to be uncommented. | John the Ripper 1.7.6+ includes built-in parallelization for multi-CPU and/or multi-core systems by means of OpenMP directives.

| John the Ripper 1.7.9+ adds built-in OpenMP parallelization for traditional DES-based crypt(3), BSDI-style DES-based crypt(3), FreeBSD-style MD5-based crypt(3), and for LM hashes. (For 1.7.6 through 1.7.8, similar parallelization of the DES-based hashes was available with patches.) | John the Ripper 1.7.9+ adds built-in OpenMP parallelization for traditional DES-based crypt(3), BSDI-style DES-based crypt(3), FreeBSD-style MD5-based crypt(3), and for LM hashes.
