  2. Certificate revocation - Wikipedia

    en.wikipedia.org/wiki/Certificate_revocation

    Let's Revoke uses bit vectors of revocation statuses (called certificate revocation vectors, or CRVs) to allow large amounts of revocation statuses to be efficiently retrieved by clients. [4] CAs generate CRVs for their own certificates, with one CRV per expiration date. CRV maintenance for CAs is linear in the number of certificates issued ...

  3. 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    In cryptography, a certificate revocation list (CRL) is "a list of digital certificates that have been revoked by the issuing certificate authority (CA) ...

  4. Public key infrastructure - Wikipedia

    en.wikipedia.org/wiki/Public_key_infrastructure

    Without revocation, an attacker would be able to exploit such a compromised or mis-issued certificate until expiry. [15] Hence, revocation is an important part of a public key infrastructure. [16] Revocation is performed by the issuing certificate authority, which produces a cryptographically authenticated statement of revocation. [17]

  5. Online Certificate Status Protocol - Wikipedia

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

    The OCSP responder uses the certificate serial number to look up the revocation status of Alice's certificate. The OCSP responder looks in a CA database that Carol maintains. In this scenario, Carol's CA database is the only trusted location where a compromise to Alice's certificate would be recorded.

  6. X.509 - Wikipedia

    en.wikipedia.org/wiki/X.509

    X.509 also defines certificate revocation lists, which are a means to distribute information about certificates that have been deemed invalid by a signing authority, as well as a certification path validation algorithm, which allows for certificates to be signed by intermediate CA certificates, which are, in turn, signed by other certificates ...

  7. OpenSSL - Wikipedia

    en.wikipedia.org/wiki/OpenSSL

    OpenSSL is a software library for applications that provide secure communications over computer networks against eavesdropping, and identify the party at the other end. It is widely used by Internet servers, including the majority of HTTPS websites. OpenSSL contains an open-source implementation of the SSL and TLS protocols.

  8. Certificate authority - Wikipedia

    en.wikipedia.org/wiki/Certificate_authority

    Without revocation, an attacker would be able to exploit such a compromised or misissued certificate until expiry. [31] Hence, revocation is an important part of a public key infrastructure. [32] Revocation is performed by the issuing CA, which produces a cryptographically authenticated statement of revocation. [33]

  9. PKCS 7 - Wikipedia

    en.wikipedia.org/wiki/PKCS_7

    X.509 public key certificates, X.509 CRLs In cryptography , PKCS #7 ("PKCS #7: Cryptographic Message Syntax", "CMS") is a standard syntax for storing signed and/or encrypted data. PKCS #7 is one of the family of standards called Public-Key Cryptography Standards ( PKCS ) created by RSA Laboratories .
