Type it into a hex editor and look at the ascii view. Eg, the first Code is BDA24E5EA0AD29FE5A49F9794128241A4AF7FD01EC846DE458 8A6AB . What that represents nobody could say. but if you convert the other two codes there maybe something that makes sense when you compare them (if you know the origin, about which you have told us nothing)

Git

Hi,

These are only BigNumbers, that could be used by many..many algorithms you have to check the xRefs with IDA and watch how they are used, and after you can detect the Algorithm.

At the actual state they are only common numbers, that may represent domain parameters, exponents etc etc..

You can also try with a Crypto Analyzer such as Kanal, RDG/Peid x3chun scanner etc.. but they are non 100% secure, so the best approach remains backtracing

Regards,
