       crl - CRL utility


       openssl crl [-inform PEM|DER] [-outform PEM|DER] [-text] [-in filename] [-out filename]
       [-noout] [-hash] [-issuer] [-lastupdate] [-nextupdate] [-CAfile file] [-CApath dir]


       The crl command processes CRL files in DER or PEM format.


       -inform DER|PEM
           This specifies the input format. DER format is DER encoded CRL structure. PEM (the
           default) is a base64 encoded version of the DER form with header and footer lines.

       -outform DER|PEM
           This specifies the output format, the options have the same meaning as the -inform

       -in filename
           This specifies the input filename to read from or standard input if this option is not

       -out filename
           specifies the output filename to write to or standard output by default.

           print out the CRL in text form.

           don't output the encoded version of the CRL.

           output a hash of the issuer name. This can be use to lookup CRLs in a directory by
           issuer name.

           output the issuer name.

           output the lastUpdate field.

           output the nextUpdate field.

       -CAfile file
           verify the signature on a CRL by looking up the issuing certificate in file

       -CApath dir
           verify the signature on a CRL by looking up the issuing certificate in dir. This
           directory must be a standard certificate directory: that is a hash of each subject
           name (using x509 -hash) should be linked to each certificate.


       The PEM CRL format uses the header and footer lines:

        -----BEGIN X509 CRL-----

        -----END X509 CRL-----


       Convert a CRL file from PEM to DER:

        openssl crl -in crl.pem -outform DER -out crl.der

       Output the text form of a DER encoded certificate:

        openssl crl -in crl.der -text -noout


       Ideally it should be possible to create a CRL using appropriate options and files too.
