NAME
       openssl-pkcs7 - PKCS#7 command

SYNOPSIS
       openssl pkcs7 [-help] [-inform DER|PEM] [-outform DER|PEM] [-in filename] [-out filename] [-print]
       [-print_certs] [-quiet] [-text] [-noout] [-engine id] [-provider name] [-provider-path path]
       [-provparam [name:]key=value] [-propquery propq]

DESCRIPTION
       This command processes PKCS#7 files.  Note that it only understands PKCS#7 v 1.5 as specified in IETF
       RFC 2315.  It cannot currently parse CMS as described in IETF RFC 2630.

OPTIONS
       -help
	   Print out a usage message.

       -inform DER|PEM, -outform DER|PEM
	   The input and formats; the default is PEM.  See openssl-format-options(1) for details.

	   The data is a PKCS#7 Version 1.5 structure.

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

       -out filename
	   Specifies the output filename to write to or standard output by default.

       -print
	   Print out the full PKCS7 object.

       -print_certs
	   Prints out any certificates or CRLs contained in the file. They are preceded by their subject and
	   issuer names in one line format.

       -quiet
	   When	 used  with  -print_certs,  prints  out	 just the PEM-encoded certificates without any other
	   output.

       -text
	   Prints out certificate details in full rather than just subject and issuer names.

       -noout
	   Don't output the encoded version of the PKCS#7 structure  (or  certificates	if  -print_certs  is
	   set).

       -engine id
	   See "Engine Options" in openssl(1).	This option is deprecated.

       -provider name
       -provider-path path
       -provparam [name:]key=value
       -propquery propq
	   See "Provider Options" in openssl(1), provider(7), and property(7).

EXAMPLES
       Convert a PKCS#7 file from PEM to DER:

	openssl pkcs7 -in file.pem -outform DER -out file.der

       Output all certificates in a file:

	openssl pkcs7 -in file.pem -print_certs -out certs.pem
