Description:
UnHash project is a program that tries to find a collision in
a given hash. The hash can be either MD5 or SHA1, and the program
will auto-detect which one is given.
To see usage just run it without any arguments.
The idea to write such a program came to me when I was playing
the NGSEC (www.ngsec.com) games. Some levels required to find the
original username/password string from SHA1 and MD5 hashes of them.
There existed
an MD5 cracker already, but nothing for SHA1. So, while I was
writing one
from rfc code it seemed like a good idea to put both crackers
into one.
I also noticed that the MD5 cracker used OpenSSL's libs so I
also added support for openssl, which is much faster than rfc's.
OpenSSL support will compile by default unless you uncomment the
define for rfc in config.h.
Requirements:
· GNU make (gmake on solaris)
· GNU compiler (gcc)
It is strongly suggested to have OpenSSL installed. If you're
using Red Hat's system then you'll need both of openssl packages
(openssl + devel).
However, if you don't have OpenSSL you can uncomment the
define in config.h and run 'make rfc'. This will use the code
from RFC-1321 and RFC-1810 for MD5, and RFC-3174 for SHA1.
What's New in This Release:
· The statistics signal handler was changed.
· It can be invoked by hitting any key.
· Minor code cleanup and some bugfixes were done.
