15.3.4
The Certificate Revocation List (CRL) is used to verify whether or not the computers dialing in hold valid
certificates.
The CRL contains the serial numbers of certificates that should be blocked. So if you wish to withdraw
someone
’s dial-in access rights to the router or the PLC behind it, you just need to create a CRL. XCA
makes this easy.
