Agent skill

ciphey

Automatic decryption and decoding tool using AI. Use when user says "解密", "decrypt", "decode", "crack", "破解密码", or provides encrypted/encoded text that needs to be deciphered. Supports 50+ encryption types including Base64, Caesar, Vigenere, XOR, Morse code, binary, hashes, and more.

Ciphey

Automatic decryption/decoding tool that uses AI to detect and crack encryption.

Usage

Run the decrypt script:

bash
python3 ~/.claude/skills/ciphey/scripts/decrypt.py "<ciphertext>" [-q]

Parameters:

  • ciphertext: The encrypted/encoded text to decrypt (required)
  • -q: Quiet mode, suppress progress output (optional)

Examples

Decrypt Base64:

bash
python3 ~/.claude/skills/ciphey/scripts/decrypt.py "SGVsbG8gV29ybGQh"
# Output: Hello World!

Decrypt with quiet mode:

bash
python3 ~/.claude/skills/ciphey/scripts/decrypt.py "Uryyb Jbeyq!" -q
# Output: Hello World! (Caesar/ROT13)

Supported Encryptions

  • Encodings: Base64, Base32, Base16, Binary, Hex, Octal, ASCII, URL encoding
  • Classical Ciphers: Caesar, ROT13, Vigenere, Affine, Atbash, Playfair
  • Modern: XOR, Repeating-key XOR
  • Hashes: MD5, SHA1, SHA256, SHA512 (detection)
  • Other: Morse code, NATO phonetic, Braille, and 40+ more

Installation

The script auto-detects and uses available installation:

  1. Direct: If ciphey command exists
  2. Docker: Uses remnux/ciphey image (recommended)
  3. Homebrew: brew install ciphey
  4. pipx: pipx install ciphey

Notes

  • Uses AI to automatically detect encryption type
  • Most decryptions complete in under 3 seconds
  • Requires Python 3.7+
