.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
The \fBpkcs7\fR command processes PKCS#7 files in \s-1DER\s0 or \s-1PEM\s0 format.
.SH "COMMAND OPTIONS"
.IX Header "COMMAND OPTIONS"
.Ip "\fB\-inform DER|PEM\fR" 4
.IX Item "-inform DER|PEM"
This specifies the input format. \fB\s-1DER\s0\fR format is \s-1DER\s0 encoded PKCS#7
v1.5 structure.\fB\s-1PEM\s0\fR (the default) is a base64 encoded version of
the \s-1DER\s0 form with header and footer lines.
.Ip "\fB\-outform DER|PEM\fR" 4
.IX Item "-outform DER|PEM"
This specifies the output format, the options have the same meaning as the 
\&\fB\-inform\fR option.
.Ip "\fB\-in filename\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 filename\fR" 4
.IX Item "-out filename"
specifies the output filename to write to or standard output by
default.
.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\-text\fR" 4
.IX Item "-text"
prints out certificates 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
is \fB\-print_certs\fR is set).
.SH "EXAMPLES"
.IX Header "EXAMPLES"
Convert a PKCS#7 file from \s-1PEM\s0 to \s-1DER:\s0
.PP
.Vb 1
\& openssl pkcs7 -in file.pem -outform DER -out file.der
.Ve
Output all certificates in a file:
.PP
.Vb 1
\& openssl pkcs7 -in file.pem -print_certs -out certs.pem
.Ve
.SH "NOTES"
.IX Header "NOTES"
The \s-1PEM\s0 PKCS#7 format uses the header and footer lines:
.PP
.Vb 2
\& -----BEGIN PKCS7-----
\& -----END PKCS7-----
.Ve
For compatibility with some CAs it will also accept:
.PP
.Vb 2
\& -----BEGIN CERTIFICATE-----
\& -----END CERTIFICATE-----
.Ve
.SH "RESTRICTIONS"
.IX Header "RESTRICTIONS"
There is no option to print out all the fields of a PKCS#7 file.
.PP
This PKCS#7 routines only understand PKCS#7 v 1.5 as specified in \s-1RFC2315\s0 they 
cannot currently parse, for example, the new \s-1CMS\s0 as described in \s-1RFC2630\s0.
