/r/security - General security subreddit.Other subreddits that may be of interest: Libera Chat's IRC:s #crypto - ( IRC protocol URL).Our monthly cryptography wishlist threads!.Threads on starting in crypto one & two.Remember that this sub is focused on the algorithms, and isn't political. See the list of related subs below for alternatives.

Maybe try /r/cryptocurrency? Political news also very rarely belong here.

Systems that use crypto are not necessarily relevant here, e.g.

You may ask for help to understand it, but you should disclose the source.

Don't use this sub to cheat on competitions or challenges! You're expected to solve such problems yourself.

Familiarize yourself with the following before posting a question about a novel cryptosystem, or else the risk is nobody will take their time to answer:.

'Crack this cipher' challenges also belong in /r/codes unless they're based on interesting crypto implementation bugs, e.g.

Do not ask people to break your cryptosystem without first sharing the algorithm.

(Rule of thumb: If a desktop computer can break a code in less than an hour, it's not strong crypto.) You're probably looking for /r/codes.

Codes, simple ciphers, ARGs, and other such 'weak crypto' don't belong here.

This subreddit is intended for links and discussions surrounding the theory and practice of modern and strong cryptography. Cryptography lives at an intersection of math and computer science. is the art of creating mathematical / information theoretic assurances for who can do what with data, including but not limited to the classical example of encrypting messages so that only the key-holder can read it.
