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

SYNOPSIS
       openssl crl2pkcs7 [-help] [-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.

OPTIONS
       -help
	   Print out a usage message.

       -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. The default format is PEM.

       -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. The default
	   format is PEM.

       -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.
