Sub_402BB0 of the SSG keygen is responsible for filling the necessary bitfields in the platform and feature DWORDs and then calling the transforms and MD5 function at the end. I'm assuming it does 2 MD5 hashes and takes values from both hashes to compile the activation key.
So the PIX algorithm is fairly simple, unfortunately I do not have the skills to determine how the existing keygen generates a 5 tuple key from MD5. If you're smart enough to reverse the algorithm, you're smart enough to realize the consequences of doing so U:H Releasing the algorithm to the public would be catastrophic and would only smear the efforts of everyone to date who has released tools designed to help you (SSG). You can trace each function at will to discern the contents of the array. The primary DialogFunction calls a procedure which is responsible for calling the separate transformation procedures.Ĭisco ASA keygen(5505 OR 5510) - posted in IOS and related Cisco files: Hidden Content Youll be able to see the hidden content once you press the thanks button. If you want to see what is happening, use OllyDbg to trace the SSG tool as it is running. Both the assembly code and the decompiled source of the SSG tool clearly show the four transformations made to the MD5 input buffer before the MD5 function is called. SSG keygen) and create your own tool from it. A much smarter strategy would be to figure out how the existing tools work (ie. But honestly, what do you think will happen if you make it public?Īs soon as the algorithm is deconstructed and made public, Cisco will be forced to change it and we all lose. I know you are all itching to figure out the ASA licensing algorithm. Hey guys, As someone who figured out the PIX and ASA algorithms many years ago, I wanted to add my own commentary here.
