PKCS7(1)			    OpenSSL			      PKCS7(1)

NAME
       openssl-pkcs7, pkcs7 - PKCS#7 utility

SYNOPSIS
       openssl pkcs7 [-help] [-inform PEM|DER] [-outform PEM|DER] [-in
       filename] [-out filename] [-print_certs]	[-text]	[-noout] [-engine id]

DESCRIPTION
       The pkcs7 command processes PKCS#7 files	in DER or PEM format.

OPTIONS
       -help
	   Print out a usage message.

       -inform DER|PEM
	   This	specifies the input format. DER	format is DER encoded PKCS#7
	   v1.5	structure.PEM (the default) is a base64	encoded	version	of the
	   DER form with header	and footer lines.

       -outform	DER|PEM
	   This	specifies the output format, the options have the same meaning
	   and default as the -inform option.

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

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

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

       -engine id
	   Specifying an engine	(by its	unique id string) will cause pkcs7 to
	   attempt to obtain a functional reference to the specified engine,
	   thus	initialising it	if needed. The engine will then	be set as the
	   default for all available algorithms.

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

NOTES
       The PEM PKCS#7 format uses the header and footer	lines:

	-----BEGIN PKCS7-----
	-----END PKCS7-----

       For compatibility with some CAs it will also accept:

	-----BEGIN CERTIFICATE-----
	-----END CERTIFICATE-----

RESTRICTIONS
       There is	no option to print out all the fields of a PKCS#7 file.

       This PKCS#7 routines only understand PKCS#7 v 1.5 as specified in
       RFC2315 they cannot currently parse, for	example, the new CMS as
       described in RFC2630.
