Certificate Revocation List (CRL)
A Certificate Revocation List (CRL) is a way to check the validity of an existing certificate. A
certificate may be invalid for several reasons:
• The status of the entity identified by the Certificate has changed in some way (for example,
an employee has left the company).
• The private key associated with a Certificate was stolen or compromised.
• A new certificate was issued that takes precedence over the old certificate.
If a certificate is invalid, the CA may publish the certificate on a Certificate Revocation List at
a given interval, or on an online server in a X.509 v3 database using Online Certificate Status
Protocol (OCSP). Consult your CA provider for specific details on locating a CRL file or URL.
Tip The SonicWALL security appliance supports obtaining the CRL via HTTP or manually
downloading the list.
