As others commented -- You did not disclose enough about what you

Also look at openssl (/usr/bin/openssl).

Note that the pass word tools do not decrypt they simply verify that
the encrypted hash
of the offered pass word matches the saved encrypted hash.  Implicit
in this strategy
is that it adds difficulty for pass word hackers should they capture
/etc/passwd:/etc/shadow files, pay attention to the use of the salt
parameter as well.
