Public-key cryptography

cryptosystem that uses both public and private keys

electronic document used to prove the ownership of a public key

method of exchanging cryptographic keys

system that can issue, distribute and verify digital certificates

In cryptography, X.509 is an International Telecommunication Union (ITU) standard defining the format of public key certificates. X.509 certificates are used in many Internet protocols, including TLS/SSL, which is the basis for HTTPS, the secure protocol for browsing the web. They are also used in offline applications, like electronic signatures.

Public Key Cryptography Standards (PKCS) are a group of public-key cryptography intervendor standards first developed by RSA Security, with involvement from Apple, Digital, Lotus Software, Microsoft, MIT, Nothern Telecom, and Sun Microsystems, first published in June 1991.

In law, non-repudiation is a situation where a statement's author cannot successfully dispute its authorship or the validity of an associated contract. The term is often seen in a legal setting when the authenticity of a signature is being challenged. In such an instance, the authenticity is being "repudiated".

in computing, a list of revoked certificates

form of digital signature in which the content of a message is disguised (blinded) before it is signed

cryptographic concept

cryptographic protocol enabling the sharing of a secret key over an insecure channel

In public-key cryptography, Edwards-curve Digital Signature Algorithm (EdDSA) is a digital signature scheme using a variant of Schnorr signature based on twisted Edwards curves. It is designed to be faster than existing digital signature schemes without sacrificing security. It was developed by a team including Daniel J. Bernstein, Niels Duif, Tanja Lange, Peter Schwabe, and Bo-Yin Yang. The reference implementation is public-domain software.
