cribdrag is a script for performing crib dragging attacks against ciphertext encrypted using an XOR operation with a predictable key.
This script can be used to cryptanalyze:
- One-Time Pad with reused key (XOR two ciphertexts together)
- Any stream cipher with reused key (XOR two ciphertexts together)
- Single character XOR
- Multiple character XOR
