forget about this post, it isn't possible to crack this type of arma protection (except keygen ) without valid name & serial. if you have valid name & serial, just unpack it like every arma-version.name & pass is used to decrypt code, it is not checked in plain. |

Hello,
Sorry if this is a little out of topic, but I had a very similar problem (solved) with progs protected by PcGuard. It is important to trace to the point where the sections are decrypted by some param extracted from the Name/Serial/progID..., even if they are fake. In facts, while decryption procedure occures, a CRC on the decrypted datas is computed at the same time. After the whole section is done, the CRC is compared to some reference, wich must be hard-coded, in order to be sure all was done in the right way. This check generates the second message. Now this check is very usefull because you can assemble in Olly a small loop witch increments the param and checks the CRC result (of course, the decryption routine must be a little modified in order to leave the section at his original stade at every loop). So this very fast brute-force routine will gives you the right param in few minutes (maybe hours). After that, restart all, bypass the first Name/Serial check, put the right param just founded, and now you can trace to the OEP ![]() I don't know if this is usefull for Armadillo, let me know... good work !
