Ciphey

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

Usage

Run the decrypt script:

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:

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

Decrypt with quiet mode:

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+
