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 ?
