PROGRAM:
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.
