I have a string that looks like this. That I need to decode.
DE9F6B7AB96AA0D5B01F8E51BE2B4D8951CC2C8A10E42F5EA1DB089D677BF15E
I am not sure what method is being used to encode this string so if someone could tell me what the method is and how to decode it?
From the length of the string (64 hex digits = 32 bytes = 32 x 8 = 256 bits), it appears to be SHA256 hash or one of these hashes: BLAKE/GOST/Snefru(256) (if they are still in use)
By theory a hash, if it is created using a cryptographic hash function, is supposed to be “infeasible to generate” back the original clear text. So, I doubt if you could decode this. Crackstation yielded the type as “unknown” and failed to get its cleartext.
