.SH DESCRIPTION
.IX Header "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.
.SH OPTIONS
.IX Header "OPTIONS"
.IP \fB\-help\fR 4
.IX Item "-help"
Print out a usage message.
.IP "\fB\-inform\fR \fBDER\fR|\fBPEM\fR, \fB\-outform\fR \fBDER\fR|\fBPEM\fR" 4
.IX Item "-inform DER|PEM, -outform DER|PEM"
The input and formats; the default is \fBPEM\fR.
See \fBopenssl\-format\-options\fR\|(1) for details.
.Sp
The data is a PKCS#7 Version 1.5 structure.
.IP "\fB\-in\fR \fIfilename\fR" 4
.IX Item "-in filename"
This specifies the input filename to read from or standard input if this
option is not specified.
.IP "\fB\-out\fR \fIfilename\fR" 4
.IX Item "-out filename"
Specifies the output filename to write to or standard output by
default.
.IP \fB\-print\fR 4
.IX Item "-print"
Print out the full PKCS7 object.
.IP \fB\-print_certs\fR 4
.IX Item "-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.
.IP \fB\-quiet\fR 4
.IX Item "-quiet"
When used with \-print_certs, prints out just the PEM-encoded 
certificates without any other output.
.IP \fB\-text\fR 4
.IX Item "-text"
Prints out certificate details in full rather than just subject and
issuer names.
.IP \fB\-noout\fR 4
.IX Item "-noout"
Don't output the encoded version of the PKCS#7 structure (or certificates
if \fB\-print_certs\fR is set).
.IP "\fB\-engine\fR \fIid\fR" 4
.IX Item "-engine id"
See "Engine Options" in \fBopenssl\fR\|(1).
This option is deprecated.
.IP "\fB\-provider\fR \fIname\fR" 4
.IX Item "-provider name"
.PD 0
.IP "\fB\-provider\-path\fR \fIpath\fR" 4
.IX Item "-provider-path path"
.IP "\fB\-propquery\fR \fIpropq\fR" 4
.IX Item "-propquery propq"
.PD
See "Provider Options" in \fBopenssl\fR\|(1), \fBprovider\fR\|(7), and \fBproperty\fR\|(7).
.SH EXAMPLES
.IX Header "EXAMPLES"

.PP
.Vb 1
\& openssl pkcs7 \-in file.pem \-outform DER \-out file.der
.Ve
.PP
Output all certificates in a file:
.PP
.Vb 1
\& openssl pkcs7 \-in file.pem \-print_certs \-out certs.pem
.Ve
