Evidence-Ranked Cipher Identifier

Deterministic fingerprints shortlist likely encodings and ciphers. Constrained OpenCode review can explain—but cannot invent or override—the candidates.

Ciphertext

Paste the message exactly as supplied. Spaces, separators, casing, and padding are useful evidence.

Identification is probabilistic. Similar cipher families can have identical surface statistics, especially with short messages. Use challenge hints, known plaintext, key material, and attempted decoding to confirm a hypothesis.
