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

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 certificates 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 certificates 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 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 utility 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.
