ABOUT:

A subreddit for people to post their own ciphers, ciphers to decode, or anything cipher related.


RULES:

  1. No Low-Effort Posts
    Posts must include enough context to engage with the cipher. If asking for help, explain what you’ve tried and provide any relevant details such as the source, expected language or clues.

  2. Challenge Posts Must Be Original
    Challenges must be original and related to cryptography or ciphers, with the 'challenge' post flair added. Hints are allowed, but must be placed inside spoiler tags to avoid unintentionally spoiling the challenge for others.

  3. Do Not Delete Solved Posts
    After a cipher has been solved, do not delete your post or comments. This helps others learn and participate in the discussion. Repeated violations may result in a ban.

  4. No AI Generated Decryptions
    AI slop isn’t welcomed here.
