Hashes

Author: Marin Radu

Description

Hash 'CSCTF' with MD5, SHA256 a file, crack a SHA1 hash, then SHA512 a file for the flag.

Requirements

• Hashing
• Cracking

Solve

Execute these steps:

1. MD5: Hash 'CSCTF', save to ctf.txt.
2. SHA256: Hash ctf.txt (not needed for the solution).
3. Crack SHA1: 6e6a4cd1b4c953e652628742c9bf6e2e9a544b5d, unnecessary since it's SHA1 :) . Append result to ctf.txt.
4. SHA512: Hash ctf.txt for the final flag.
