Known plaintext attack


Recommended Posts

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 ?

No clue what you're talking about, but if it's cracking a hash you want to reverse, try throwing it in a file and cracking with JTR. John will tell you what kind of hash it thinks it is and can try multiple hash attacks against it without the need to specify the hash like hashcat will want. if it's a wireless key, might need to convert it for cracking.

here the Hash 2B7FEF0F82A51EEA6A6922ADE609DB288E676F591B28D5F7241DBF84F0AE2E20A00A73A52234BDE76492A01EDD8D13B722343E6F9C5DF8AA18922A92D714FC66 

What's the context of the source of this hash? Known password length? Do you know what characters would be involved (uppercase, lowercase, numbers, symbols)?
