crypto-identifier

Ferramenta de criptografia para pentest e CTF: tenta decifrar dados usando múltiplos algoritmos e modos de encadeamento de blocos. Útil para uma verificação rápida de texto cifrado desconhecido e dicionário de chaves.

Algoritmos Suportados :

  • AES
  • ARC2
  • ARC4
  • Blowfish
  • CAST
  • DES
  • DES3
  • XOR

Modos suportados :

  • ECB
  • CBC
  • CFB
  • OFB

Usage:

root@kitploit:~
python ./crypto_identifier.py --help
usage: crypto_identifier.py [-h] --input INPUT [--key KEY] [--keys KEYS]
                            [--printable] [--grep GREP]
                            [--algo {ARC4,CAST,AES,XOR,ARC2,DES,Blowfish,DES3}]
                            [--mode {ECB,CBC,CFB,OFB}]

optional arguments:
  -h, --help            show this help message and exit
  --input INPUT, -i INPUT
                        input string (base64)
  --key KEY, -k KEY     key string
  --keys KEYS, -ks KEYS
                        keys file
  --printable, -p       display only printable results
  --grep GREP, -g GREP  grep string in results
  --algo {ARC4,CAST,AES,XOR,ARC2,DES,Blowfish,DES3}, -a {ARC4,CAST,AES,XOR,ARC2,DES,Blowfish,DES3}
                        cipher algo to use
  --mode {ECB,CBC,CFB,OFB}, -m {ECB,CBC,CFB,OFB}
                        block chaining mode to use
