  2. Digital signature - Wikipedia

    en.wikipedia.org/wiki/Digital_signature

    Definition. A digital signature scheme typically consists of three algorithms: A key generation algorithm that selects a private key uniformly at random from a set of possible private keys. The algorithm outputs the private key and a corresponding public key. A signing algorithm that, given a message and a private key, produces a signature.

  3. Public key certificate - Wikipedia

    en.wikipedia.org/wiki/Public_key_certificate

    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 ...

  4. Code signing - Wikipedia

    en.wikipedia.org/wiki/Code_signing

    Code signing is the process of digitally signing executables and scripts to confirm the software author and guarantee that the code has not been altered or corrupted since it was signed. The process employs the use of a cryptographic hash to validate authenticity and integrity. [1] Code signing was invented in 1995 by Michael Doyle, as part of ...

  5. Certificate revocation list - Wikipedia

    en.wikipedia.org/wiki/Certificate_revocation_list

    In cryptography, a certificate revocation list (CRL) is "a list of digital certificates that have been revoked by the issuing certificate authority (CA) before their scheduled expiration date and should no longer be trusted". [1]

  6. Digital Signature Algorithm - Wikipedia

    en.wikipedia.org/wiki/Digital_Signature_Algorithm

    Digital Signature Algorithm. The Digital Signature Algorithm (DSA) is a public-key cryptosystem and Federal Information Processing Standard for digital signatures, based on the mathematical concept of modular exponentiation and the discrete logarithm problem. In a public-key cryptosystem, two keys are generated: data can only be encrypted with ...

  7. Online Certificate Status Protocol - Wikipedia

    en.wikipedia.org/wiki/Online_Certificate_Status...

    The Online Certificate Status Protocol (OCSP) is an Internet protocol used for obtaining the revocation status of an X.509 digital certificate. [2] It is described in RFC 6960 and is on the Internet standards track. It was created as an alternative to certificate revocation lists (CRL), specifically addressing certain problems associated with ...

  8. Qualified website authentication certificate - Wikipedia

    en.wikipedia.org/wiki/Qualified_website...

    A qualified website authentication certificate (QWAC certificate) is a qualified digital certificate under the trust services defined in the European Union eIDAS Regulation. A 2016 European Union Agency for Cybersecurity report proposed six strategies and twelve recommended actions as an escalated approach that targets the most important ...

  9. Card Verifiable Certificate - Wikipedia

    en.wikipedia.org/wiki/Card_Verifiable_Certificate

    Card Verifiable Certificate. Card Verifiable Certificates (CVC) are digital certificates that are designed to be processed by devices with limited computing power such as smart cards. This is achieved by using simple type–length–value (TLV) encoding with fixed fields. Fixed fields means that each field in the certificate is of fixed, or ...
