TLS certificate validation using CRL # Only CRL v1 with basic fields is currently supported. This means Acra will be able to download CRL, verify it, and search for a certificate serial number there. But more advanced features like CRL extensions (including delta CRLs) are not handled yet. CRL-related flags and their descriptions. Works for acra-connector, acra-server and acra-translator. --tls_crl_url=<url> URL of the Certificate Revocation List (CRL) to use.
