Crypto tool for pentest and ctf : try to uncipher data using multiple algorithms and block chaining modes. Usefull for a quick check on unknown cipher text and key dictionary
Supported Algorithms :
- AES
- ARC2
- ARC4
- Blowfish
- CAST
- DES
- DES3
- XOR
Supported modes :
- ECB
- CBC
- CFB
- OFB
python ./crypto_identifier.py --help
