cryptography (noun). The discipline concerned with communication security (eg, confidentiality of messages, integrity of messages, sender authentication, non-repudiation of messages, and many other related issues), regardless of the used medium such as pencil and paper or computers.

This community is for links about and discussion of cryptography specifically. For privacy technology more generally, use !privacy.

This community is explicitly not about cryptocurrency; see !crypto for that.

This is a technical but quite informative article, nominally about which elliptic curves have good security properties, but also discusses the intentions behind using EC instead of older systems like RSA (basically, EC is safer against some known classes of attacks).

Posting partly because EC vs RSA came up here a few days ago.

Bitcoin uses NIST P256 iirc, so you can possibly turn implementation mistakes into cash. :)
