CRL Certificate:<\/strong> In the field of cryptography, a CRL certificate (abbreviation for certificate revocation list) is a list of digital certificates that have been revoked by issuing a CA before the scheduled date of expiry and hence, it should not be trusted.<\/p>\n

What is a CRL Certificate?<\/h2>\n

CRL is the abbreviation for Certificate Revocation List. Its definition, as per the National Institute of Standards and Technology (NIST) is as follows: \u201cCRL is a list of revoked public-key certificates created and digitally signed by a Certification Authority (CA)\u201d.<\/p>\n

However, the Internet Engineering Task Force\u2019 RFC 5280 profile defines CRL as: \u201cA time-stamped and signed data structure that a certificate authority (CA) or CRL issuer periodically issues to communicate the revocation status of affected digital certificates.\u201d<\/p>\n

Why do you need a CRL?<\/h3>\n

As the name implies, a CRL distinguishes untrusted certificates from trusted ones. Moreover, the certification revocation lists are offered on an hourly, daily or weekly basis as per the needs of the provider.<\/p>\n

CRL Implications<\/h3>\n

When the CA revokes a certificate in a particular website, the visitors of the website are shown a warning before they can access the content. The warning is as follows:<\/p>\n

\u201cYour connection is not private\u201d attackers might be trying to steal your information from (website url)…\u201d<\/p>\n

If you are a business, then the above message is disconcerting as it can drive away visitors and potential customers from your website.<\/p>\n
