NAME

6       openssl-pkcs7, pkcs7 - PKCS#7 utility
7

SYNOPSIS

9       openssl pkcs7 [-help] [-inform PEM|DER] [-outform PEM|DER] [-in
10       filename] [-out filename] [-print_certs] [-text] [-noout] [-engine id]
11

DESCRIPTION

13       The pkcs7 command processes PKCS#7 files in DER or PEM format.
14

OPTIONS

16       -help
17           Print out a usage message.
18
19       -inform DER|PEM
20           This specifies the input format. DER format is DER encoded PKCS#7
21           v1.5 structure.PEM (the default) is a base64 encoded version of the
22           DER form with header and footer lines.
23
24       -outform DER|PEM
25           This specifies the output format, the options have the same meaning
26           and default as the -inform option.
27
28       -in filename
29           This specifies the input filename to read from or standard input if
30           this option is not specified.
31
32       -out filename
33           Specifies the output filename to write to or standard output by
34           default.
35
36       -print_certs
37           Prints out any certificates or CRLs contained in the file. They are
38           preceded by their subject and issuer names in one line format.
39
40       -text
41           Prints out certificates details in full rather than just subject
42           and issuer names.
43
44       -noout
45           Don't output the encoded version of the PKCS#7 structure (or
46           certificates is -print_certs is set).
47
48       -engine id
49           Specifying an engine (by its unique id string) will cause pkcs7 to
50           attempt to obtain a functional reference to the specified engine,
51           thus initialising it if needed. The engine will then be set as the
52           default for all available algorithms.
53

EXAMPLES

55       Convert a PKCS#7 file from PEM to DER:
56
57        openssl pkcs7 -in file.pem -outform DER -out file.der
58
59       Output all certificates in a file:
60
61        openssl pkcs7 -in file.pem -print_certs -out certs.pem
62

NOTES

64       The PEM PKCS#7 format uses the header and footer lines:
65
66        -----BEGIN PKCS7-----
67        -----END PKCS7-----
68
69       For compatibility with some CAs it will also accept:
70
71        -----BEGIN CERTIFICATE-----
72        -----END CERTIFICATE-----
73

RESTRICTIONS

75       There is no option to print out all the fields of a PKCS#7 file.
76
77       This PKCS#7 routines only understand PKCS#7 v 1.5 as specified in
78       RFC2315 they cannot currently parse, for example, the new CMS as
79       described in RFC2630.
