Does CRL contain expired certificates?
An expired certificate is rejected at the first step of the authentication process, well before the CRL is checked, so there’s no need to include it there. Furthermore, certificates that reach their expiration date while on a CRL are automatically removed from the list.
What is CRL used for?
It is a type of blocklist that includes certificates that should no longer be trusted and is used by various endpoints, including web browsers, to verify if a certificate is valid and trustworthy. The CRL file is signed by the CA to prevent tampering.

Why is a certificate revocation list ( CRL ) necessary?
The CRL is populated by a certificate authority (CA), another part of the PKI. Importantly, only the CA that issued the certificate has the power to revoke it and place it on the CRL. Why is a Certificate Revocation List Necessary? Without a CRL, there’s no way for the PKI to know whether a certificate has been revoked before its expiration.
How to check the status of a CRL certificate?
To check the status of a certificate using a CRL, the client reaches out to the CA (or CRL issuer) and downloads its certificate revocation list. After doing this, it then must search through the entire list for that individual certificate. This is not only cumbersome but it’s also slow.
Why is a CRL important in a PKI?
A CRL is an important component of a public key infrastructure (PKI), a system designed to identify and authenticate users to a shared resource like a Wi-Fi network. The CRL is populated by a certificate authority (CA), another part of the PKI. Importantly, only the CA that issued the certificate has the power to revoke it and place it on the CRL.
What’s the difference between CT log and CRL?
A CT log is, essentially, a certificate inventory for your domain. But this doesn’t tell you whether a certificate is revoked. CRLs, on the other hand, are about informing clients whenever they revoke a certificate. But they don’t include a list of every certificate that a CA issues for your domain.
