Certificate Revocation Reason Codes
What are the reasons why a X.509 certificate got revoked?
When a certificate CA publishes a CRL (Certificate Revocation List) file with a list of revoked certificates, a revocation reason code will be provided for each revocation entry.
There are several reason codes commonly used in CRL files:
As you can see, the most serious reason is the "2 - CA Compromise". In this case, all X.509 certificates issued by this CA must be revoked immediately. Using a certificate whose CA private key was compromized is extremely dangerous.
