Choose a descriptive title. Examples of what NOT to use:
Cipher I just came up with
My friend just sent me this
Please help me solve this!!
Tell us context: where a code originated, any clues you might have, the language or format the plaintext might use, and any technique you already tried.
If you are posting a photo of writing, you must provide a transcription (text version).
If the writing uses symbols you can't type, simply use A every time the first symbol appears, B every time the second symbol appears, and so on.
Pay attention to formatting. If you use a character like _ or ` or ^ you need to type a \ before it or Reddit will corrupt your ciphertext.
If your ciphertext contains special characters, in order that it displays correctly you can encode it first (for instance using Base64). Alternatively use a Code Block.
Posting your own custom cipher? You must provide enough example text or there is no hope of anyone solving it. It should be at least a paragraph. Give hints.
You will be BANNED if you delete your post after a solution has been provided.
Do not post codes or ciphers from ongoing competitions (CTFs, treasure hunts etc.). Such posts will be removed. Trying to circumvent this rule may get you BANNED.
Your account must be older than 24 hours, or your post will be automatically deleted. This is to reduce spamming.
If your bot is not auto-banned on r/codes, it will be banned by a moderator. You can still have a bot on other subreddits; just don't use a bot here.
Please, refrain from posting decryptions generated with ChatGPT and similar AI programs. Such posts and comments will be removed. Repeated breaking of this rule will get you BANNED.
If you have read and understood these rules, include ROT-13 encrypted form of the text "I followed the rules" in your post.
