Public key fingerprint. In public-key cryptography, a public key fingerprint is a short sequence of bytes used to identify a longer public key. Fingerprints are created by applying a cryptographic hash function to a public key. Since fingerprints are shorter than the keys they refer to, they can be used to simplify certain key management tasks.
Multi-factor authentication is typically deployed in access control systems through the use, firstly, of a physical possession (such as a fob, keycard, or QR-code displayed on a device) which acts as the identification credential, and secondly, a validation of one's identity such as facial biometrics or retinal scan.
Public key certificate. In cryptography, a public key certificate, also known as a digital certificate or identity certificate, is an electronic document used to prove the validity of a public key. [1][2] The certificate includes the public key and information about it, information about the identity of its owner (called the subject), and the ...
In cryptography, X.509 is an International Telecommunication Union (ITU) standard defining the format of public key certificates. [1] X.509 certificates are used in many Internet protocols, including TLS/SSL, which is the basis for HTTPS, [2] the secure protocol for browsing the web. They are also used in offline applications, like electronic ...

Key server (cryptographic) In computer security, a key server is a computer that receives and then serves existing cryptographic keys to users or other programs. The users' programs can be running on the same network as the key server or on another networked computer. The keys distributed by the key server are almost always provided as part of ...
