=head1 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.

=head1 OPTIONS

=over 4

=item B<-help>

Print out a usage message.

=item B<-inform> B<DER>|B<PEM>, B<-outform> B<DER>|B<PEM>

The input and formats; the default is B<PEM>.
See L<openssl-format-options(1)> for details.

The data is a PKCS#7 Version 1.5 structure.

=item B<-in> I<filename>

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

=item B<-out> I<filename>

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

=item B<-print>

Print out the full PKCS7 object.

=item B<-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.

=item B<-quiet>

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

=item B<-text>

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

=item B<-noout>

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