Claude-skill-registry 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:

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:

Direct: If
```
ciphey
```
command exists
Docker: Uses
```
remnux/ciphey
```
image (recommended)
Homebrew:
```
brew install ciphey
```
pipx:
```
pipx install ciphey
```

Notes

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