Hello to all and thank you in advance.
I've been working on UltraEdit v 9.00a and to simply bypass the protection is done with a little tutorial help and a lot of hours in front of SI. My question is can serial fishing be done when it's being encrypted(I think it's being encrypted) and checked against parts of the fake serial/fake name given?
It seems the protection checks the value of a register(eax) against itself and if it is Zero then you're registered and if not then bad jump. I traced through calls and it seems that a Dword ptr is checked against some registers and in SI neither the D(dump) nor the "?" returned anything good from the Dwords mentioned in the call.
any help or suggestions, or if it's possible at all to do serial fishing in this particular version. BTW I checked various cracks for it and none had a key generator, only patches which goes around the protection but not generate any serials. Sorry for the long message and I hope you be able to understand my message. Thank you again.

Reversing is like solving one puzzle made up of many smaller puzzles, one puzzle at a time, to achieve a well deserved, and desired, Eurika.

Hi Beherenow,

I am pretty sure the algo is reversible... though how hard is this i dont know! I cracked it long time ago using patching but the serial has to be generated from the name given somehow!

good luck,

I was browsing and I read in "self test by Kayaker" about the hash algo in level three. I think that's what UltraEdit is doing eventhough it's a different algo because I noticed certain calls are called frequently. Thanks for the reply and the assurance.
