ChapljaVM progress update

Here's a binary obfuscated with the current CVM version. It's still in a very early development phase and the mutation complexity is very simple compared to the plans I have for later, but it should already stop quite a few newbies from easily reversing a mutated block of code.

The obfuscated application is a SHA-1 implementation with a self-test program which computes a checksum of predefined values and compares them to the expected result. The original program's source can be found here: http://www.packetizer.com/security/sha1/

Download the obfuscated binary here: http://chaplja.net/SHA1_2011_05_30.exe

Hopefully I'll be able to release a test version for testing to public soon.
