Find out Encryption

[CrackZ]

Hiya,

I recommend to everyone Cryptobench v1.0 as a great tool for testing out encryption methods, especially if you are fishing for which algorithm it might be ;-).

Generally I've found its better to either look up any constants (usually found in an initialisation function) or look up the first 4 chars of any lookup tables used in your mystery algorithm to discover if its a known crypto.

Of course you could also just compile a few examples using Crypto++ or Miracl and have a look at what various methods look like in ASM, bignum code is quite easy to identify once you've seen it a few times.
