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.
