  1. I am trying to understand how a HASH (or encrypted version of a code) is produced in some software.
  2. From now, i have identified the function responsible of generating a 128 bit value.
  3. My goal is to be able to create a software able to generate the same 128 bit value from an input string composed of 6 to 9 numbers
  4. I wonder if one of you might be able to, just by looking at the code, tells me if it is a "well known" hashing / crypting algorithm
  5. Any advice on how to be able to reuse the asm code into an autonomous program would also be appreciated (i guess it is a bit like creating a sort of keygen...)
  6. Thanks
  7. Here is the function call

  9. ; Function Call :
  10. 0916532C | push ecx | ;&key = et_ _ _ _ts (65745f5f5f5f7473) <=== Always the same (supposed to be a constant key)
  11. 0916532D | push ebp | ;&Buffer_Result <=== the 128 bit resulting value is stored here
  12. 0916532E | push esi | ;&str_user_code (6 to 8 numbers) <== my input string
