NAME

6       pkcs7 - PKCS#7 utility
7

SYNOPSIS

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

DESCRIPTION

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

COMMAND OPTIONS

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

EXAMPLES

52       Convert a PKCS#7 file from PEM to DER:
53
54        openssl pkcs7 -in file.pem -outform DER -out file.der
55
56       Output all certificates in a file:
57
58        openssl pkcs7 -in file.pem -print_certs -out certs.pem
59

NOTES

61       The PEM PKCS#7 format uses the header and footer lines:
62
63        -----BEGIN PKCS7-----
64        -----END PKCS7-----
65
66       For compatibility with some CAs it will also accept:
67
68        -----BEGIN CERTIFICATE-----
69        -----END CERTIFICATE-----
70

RESTRICTIONS

72       There is no option to print out all the fields of a PKCS#7 file.
73
74       This PKCS#7 routines only understand PKCS#7 v 1.5 as specified in
75       RFC2315 they cannot currently parse, for example, the new CMS as
76       described in RFC2630.
