No specific reason except that I do not believe the half-assed ciphers I
added are worth the work. As you'll see it's very slow and would
tremendously be sped up by proper buffering / use of the bitsliced code.
I never did this because 99% of oracle passwords seem to be equal to the
login ...
As always it *seems* to work (like the salted ldap one seemed to work,
but really did not :) on my computer, and was intended as a test of the
reverse work behind the "rediscovery" of this algorithm.
My "current" tree has all the up to date data needed for an up to date
creation of the jumbo patch, at http://btb.banquise.net/bin/myjohn.tgz.
It also should not give much work to the patch compiler as it's almost
always one more _fmt.c file, slights changes in john.c/options.c and a
few loader.c hacks.
There is also the "markov" mode which I found to be very effective on
french passwords, and "solves" some of the problems related to cracking
long passwords.
