Usage of gencrl:
        cfssl gencrl INPUTFILE CERT KEY TIME

Arguments:
        INPUTFILE:               Text file with one serial number per line, use '-' for reading text from stdin
        CERT:                    The certificate that is signing this CRL, use '-' for reading text from stdin
        KEY:                     The private key of the certificate that is signing the CRL, use '-' for reading text from stdin
        TIME (OPTIONAL):         The desired expiration from now, in seconds

Flags:
