DDEESSCCRRIIPPTTIIOONN
       The ccrrll command processes CRL files in DER or PEM format.

CCOOMMMMAANNDD OOPPTTIIOONNSS
       --iinnffoorrmm DDEERR||PPEEMM
           This specifies the input format. DDEERR format is DER encoded CRL
           structure. PPEEMM (the default) is a base64 encoded version of the DER
           form with header and footer lines.

       --oouuttffoorrmm DDEERR||PPEEMM
           This specifies the output format, the options have the same meaning
           as the --iinnffoorrmm option.

       --iinn ffiilleennaammee
           This specifies the input filename to read from or standard input if
           this option is not specified.

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

       --tteexxtt
           print out the CRL in text form.

       --nnaammeeoopptt ooppttiioonn
           option which determines how the subject or issuer names are dis-
           played. See the description of --nnaammeeoopptt in _x_5_0_9(1).

       --nnoooouutt
           don't output the encoded version of the CRL.

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

       --hhaasshh__oolldd
           outputs the "hash" of the CRL issuer name using the older algorithm
           as used by OpenSSL versions before 1.0.0.

       --iissssuueerr
           output the issuer name.

       --llaassttuuppddaattee
           output the lastUpdate field.

       --nneexxttuuppddaattee
           output the nextUpdate field.

       --CCAAffiillee ffiillee
           verify the signature on a CRL by looking up the issuing certificate
           in ffiillee

       --CCAAppaatthh ddiirr
           verify the signature on a CRL by looking up the issuing certificate
           in ddiirr. This directory must be a standard certificate directory:
           that is a hash of each subject name (using xx550099 --hhaasshh) should be
           linked to each certificate.

NNOOTTEESS
       The PEM CRL format uses the header and footer lines:

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

EEXXAAMMPPLLEESS
       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 -inform DER -text -noout

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