Detailed explanation-1: -Certificate revocation is the act of invalidating a TLS/SSL before its scheduled expiration date. A certificate should be revoked immediately when its private key shows signs of being compromised. It should also be revoked when the domain for which it was issued is no longer operational.
Detailed explanation-2: -The most common reason for revocation is when a certificate’s private key has been compromised. Other reasons for revoking a certificate include: The issuing CA has been compromised. The certificate owner no longer owns the domain for which it was issued.
Detailed explanation-3: -There are three ways to do this: from the account that issued the certificate, using a different authorized account, or using the certificate private key.
Detailed explanation-4: -A CRL is issued by a CRL issuer, which is typically the CA which also issued the corresponding certificates, but could alternatively be some other trusted authority. All CRLs have a lifetime during which they are valid; this timeframe is often 24 hours or less.
