Grab-bag pages that show up a lot in crypto challenges, but don’t fit neatly elsewhere.

Esoteric languages

Technique

Use this when a crypto task is actually: run an esolang program and then decode what it outputs.

If a challenge gives you code that does not look like a standard language:

  • Identify the esolang (Google a distinctive token).
  • Use an online interpreter or a Docker image.
  • If the output is weird, look for layered encoding/compression after execution.

Good starting list:
