NAME

       openssl-crl2pkcs7 - Create a PKCS#7 structure from a CRL and certificates

SYNOPSIS

       openssl crl2pkcs7 [-help] [-inform DER|PEM] [-outform DER|PEM] [-in filename] [-out
       filename] [-certfile filename] [-nocrl] [-provider name] [-provider-path path] [-propquery
       propq]

DESCRIPTION

       This command takes an optional CRL and one or more certificates and converts them into a
       PKCS#7 degenerate "certificates only" structure.

OPTIONS

       -help
           Print out a usage message.

       -inform DER|PEM
           The input format of the CRL; the default is PEM.  See openssl-format-options(1) for
           details.

       -outform DER|PEM
           The output format of the PKCS#7 object; the default is PEM.  See
           openssl-format-options(1) for details.

       -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 certificates from 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.

       -provider name
       -provider-path path
       -propquery propq
           See "Provider Options" in openssl(1), provider(7), and property(7).

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 different 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 and just
       certificates and an optional CRL.

       This command can be used to send certificates and CAs to Netscape as part of the
       certificate enrollment process. This involves sending the DER encoded output as MIME type
       application/x-x509-user-cert.

       The PEM encoded form with the header and footer lines removed can be used to install user
       certificates and CAs in MSIE using the Xenroll control.
