SYNOPSIS

       openssl crl2pkcs7 [-inform PEM|DER] [-outform PEM|DER] [-in filename]
       [-out filename] [-certfile filename] [-nocrl]

DESCRIPTION

       The crl2pkcs7 command takes an optional CRL and one or more certifi-
       cates and converts them into a PKCS#7 degenerate "certificates only"
       structure.

COMMAND OPTIONS

       -inform DER|PEM
           This specifies the CRL 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 PKCS#7 structure output format. DER format is
           DER encoded PKCS#7 structure.PEM (the default) is a base64 encoded
           version of the DER form with header and footer lines.

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

       -out filename
           specifies the output filename to write the PKCS#7 structure to or
           standard output by default.

       -certfile filename
           specifies a filename containing one or more certificates in PEM
           format.  All certificates in the file will be added to the PKCS#7
           structure. This option can be used more than once to read certifi-
           cates form multiple files.

       -nocrl
           normally a CRL is included in the output file. With this option no
           CRL is included in the output file and a CRL is not read from the
           input file.

EXAMPLES

       Create a PKCS#7 structure from a certificate and CRL:

        openssl crl2pkcs7 -in crl.pem -certfile cert.pem -out p7.pem

       Creates a PKCS#7 structure in DER format with no CRL from several dif-
       ferent certificates:

        openssl crl2pkcs7 -nocrl -certfile newcert.pem
               -certfile demoCA/cacert.pem -outform DER -out p7.der

NOTES

       The output file is a PKCS#7 signed data structure containing no signers
