NAME
pkcs7 - PKCS#7 utility
SYNOPSIS
openssl pkcs7
[ -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.
COMMAND OPTIONS
- -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 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.
