pkcs7 - PKCS#7 utility
|
|
|
|
=head1 SYNOPSIS
|
|
|
|
B<openssl> B<pkcs7>
|
|
[B<-inform PEM|DER>]
|
|
[B<-outform PEM|DER>]
|
|
[B<-in filename>]
|
|
[B<-out filename>]
|
|
[B<-print_certs>]
|

|
[B<-noout>]
|
|
[B<-engine id>]
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
The B<pkcs7> command processes PKCS#7 files in DER or PEM format.
|
|
|
|
=head1 COMMAND OPTIONS
|
|
|
|
=over 4
|
|
|
|
=item B<-inform DER|PEM>
|
|
|
|
This specifies the input format. B<DER> format is DER encoded PKCS#7
|
|
v1.5 structure.B<PEM> (the default) is a base64 encoded version of
|
|
the DER form with header and footer lines.
|
|
|
|
=item B<-outform DER|PEM>
|
|
|
|
This specifies the output format, the options have the same meaning as the
|
|
B<-inform> option.
|
|
|
|
=item B<-in filename>
|
|
|
|
This specifies the input filename to read from or standard input if this
|
|
option is not specified.
|
|
|
|
=item B<-out filename>
|
|
|
|
specifies the output filename to write to or standard output by
|
|
default.
|
|
|
|
=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<-text>
|
|
|
|
prints out certificates 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
|
|
is B<-print_certs> is set).
|
|
|
|
=item B<-engine id>
|
|
|
|
specifying an engine (by it's unique B<id> string) will cause B<req>
|
|
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.

=head1 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
|
|
|
|
=head1 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-----
|
|
|
|
=head1 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.
