# DON'T APPLY BOTH PATCHES AT THE SAME TIME !!

# Patch for John the Ripper to support MPI. MPI allows you to use multiple processors
# on a single system, or a cluster of systems for cracking passwords.

# The jumbo patch enables processing of many password hash types
# and ciphers that are not supported by the official JtR.
