# crypto.classical_cipher_chain

Classical cipher and encoding chain analysis

Use this skill for puzzle or training artifacts involving classical ciphers, keyboard-layout substitutions, rail fence/transposition, run-length encoded binary, Morse, Enigma-like settings, Caesar/Vigenere variants, and chained archive unlocks.

The workflow treats every decoded plaintext as both evidence and possible key material, verifies resulting passwords against actual artifacts, and documents corrections or implementation quirks.

## Guardrails

- Do not submit guessed keys as solved without verification.
- Preserve original ciphertext and correction notes.
- Avoid online exfiltration of sensitive/private ciphertext unless authorized.
