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

##RULES:

No Low-Effort or Context-Free Post- Posts must have a descriptive title and provide context. It is highly encouraged to show what you have tried in deciphering the code.
Regarding Challenges- Challenges must be original and related to cryptography or ciphers, with the 'challenge' post flair added. Hints may be provided by the poster, but must be placed in spoiler tags to avoid spoiling the challenge.
Do not delete post/answer- After a cipher has been solved, don't delete your comments or posts. This helps others learn and participate in the discussion. Repeated violations may result in a temporary or permanent ban.
