  2. Root certificate - Wikipedia

    en.wikipedia.org/wiki/Root_certificate

    The role of root certificate as in the chain of trust. In cryptography and computer security, a root certificate is a public key certificate that identifies a root certificate authority (CA). [1] Root certificates are self-signed (and it is possible for a certificate to have multiple trust paths, say if the certificate was issued by a root that ...

  3. Certificate authority - Wikipedia

    en.wikipedia.org/wiki/Certificate_authority

    Certificate authority. In cryptography, a certificate authority or certification authority (CA) is an entity that stores, signs, and issues digital certificates. A digital certificate certifies the ownership of a public key by the named subject of the certificate. This allows others (relying parties) to rely upon signatures or on assertions ...

  4. Certificate Transparency - Wikipedia

    en.wikipedia.org/wiki/Certificate_Transparency

    Certificate Transparency (CT) is an Internet security standard for monitoring and auditing the issuance of digital certificates. [1] When an internet user interacts with a website, a trusted third party is needed for assurance that the website is legitimate and that the website's encryption key is valid. This third party, called a certificate ...

  5. DNS Certification Authority Authorization - Wikipedia

    en.wikipedia.org/wiki/DNS_Certification...

    Jacob Hoffman-Andrews. DNS Certification Authority Authorization (CAA) is an Internet security policy mechanism that allows domain name holders to indicate to certificate authorities whether they are authorized to issue digital certificates for a particular domain name. It does this by means of a "CAA" Domain Name System (DNS) resource record.

  6. Code signing - Wikipedia

    en.wikipedia.org/wiki/Code_signing

    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 ...

  7. Chain of trust - Wikipedia

    en.wikipedia.org/wiki/Chain_of_trust

    The roles of root certificate, intermediate certificate and end-entity certificate as in the chain of trust. In computer security, a chain of trust is established by validating each component of hardware and software from the end entity up to the root certificate. It is intended to ensure that only trusted software and hardware can be used ...

  8. 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".

  9. Delegated Path Validation - Wikipedia

    en.wikipedia.org/wiki/Delegated_Path_Validation

    Delegated Path Validation (DPV) is a cryptographic method used to offload the task of validating the certification path of digital certificates from the client to a trusted server. [1] This process is integral to various security protocols that rely on Public Key Infrastructure (PKI). DPV aim to enhance the efficiency of certification path ...
