CRL for a revoked cert of Verisign CA. There are two different states of revocation defined in RFC 5280: Revoked A certificate is irreversibly revoked if, for example, it is discovered that the certificate authority (CA) had improperly issued a certificate, or if a private-key is thought to have been compromised.
A certificate revocation list (CRL) enumerates revoked certificates. They are cryptographically authenticated by the issuing CA. [29] CRLs have scalability issues, and rely on the client having enough network access to download them prior to checking a certificate's status. [9]
The only increased risk of OCSP stapling is that the notification of revocation for a certificate may be delayed until the last-signed OCSP response expires. As a result, clients continue to have verifiable assurance from the certificate authority that the certificate is presently valid (or was quite recently), but no longer need to ...
A certificate chain (see the equivalent concept of "certification path" defined by RFC 5280 section 3.2) is a list of certificates (usually starting with an end-entity certificate) followed by one or more CA certificates (usually the last one being a self-signed certificate), with the following properties:
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.
While Internet Explorer may still work with some AOL products and services, it's no longer supported by Microsoft and can't be updated. Because of this, we recommend you download a supported browser for a more reliable and secure experience online.
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]
