Module CRY

Cryptography Lab

Paste a signal, tune the parameters, and watch the lab sweep through common ciphers. We run every encoder and decoder in parallel and surface heuristics so you can zero in on promising leads fast.

Operations Playground

Input signal

Type or paste any text, ciphertext, or encoded payload.

The heuristics pass scores each decoder for language likelihood, entropy, and alphabet fit. Disable it for raw transform output only.

Heuristic sweep

We attempt every decoder and rank the most plausible outputs. Scores combine alphabet conformity, printable ratios, and vowel balance checks.

    Transform Library

    Each module emits both encode and decode results automatically as you type.
