I hope i hit the right forum, sorry if i didn't (-;
Anyways, i am looking for help on finding out password encryption algorithm.
I am playing with one closed system and i feel that password sub-system is quite weak.
The tests show that:
a) encrypted passwords can be decrypted, so this is not one-way hash like md5/sh1/etc;
b) it has some sort of random number inside that makes different encrypted strings for the same password each time you generate it;
c) all password letters can be split by pairs;
d) there is length(string)+1 pair in the encrypted string..
e).. which leads us to think that one of pairs might be that random number, which then helps to decode all leters;
Some generated passwords:
a => qmrq
aa => kjhfhi
aaaa => jjifiiihik
aaaaa => kdhhhkhjhmhl
