[Known plaintext attack]

here the Hash 2B7FEF0F82A51EEA6A6922ADE609DB288E676F591B28D5F7241DBF84F0AE2E20A00A73A52234BDE76492A01EDD8D13B722343E6F9C5DF8AA18922A92D714FC66

Then im now sure it a encryption with a special key, but how could i get the key? with a Known plaintext attack? how can I do that?

[Known plaintext attack]

I did test the ID hash, but the possible hashs are SHA512 and Whirlpool however when i run some online tool, they do get it right.

I got  the crib and the encrypted version, i need to find the key. The input is a 16 byte Hex sequence and the output is a 64-byte Hex sequence.

Im not sure of the type of enccryption, im thinking about SHA256-512. but im not sure

How can I do the known plaintext attack. its not a file, its a simple text

Which type of encryption do you think its possible to be ?
