NAME

7

SYNOPSIS

9       grid-cert-info -help | -usage | -version | -versions
10
11       grid-cert-info OPTIONS
12

DESCRIPTION

14       The grid-cert-info program displays information contained within a
15       certificate file. By default it shows a text representation of the
16       entire certificate. Specific facts about the certificate can be shown
17       instead by using command-line options. If any of those options are
18       used, then the default display is suppressed. This can be added to the
19       output by using the -all command-line option.
20
21       If multiple display options are included on the command-line, the facts
22       related to those will be displayed on separate lines in the order that
23       they occur. If an option is specified multiple time, that fact will be
24       displayed multiple times.
25

OPTIONS

27       The full set of command-line options to grid-cert-info are:
28
29       -help, -usage
30           Display the command-line options to grid-cert-info and exit.
31
32       -version, -versions
33           Display the version number of the grid-cert-info command. The
34           second form includes more details.
35
36       -file CERTIFICATE-FILE
37           Display information about the first certificate contained in the
38           file named by CERTIFICATE-FILE instead of the default user
39           certificate.
40
41       -rfc2253
42           Display X.509 distinguished names using the string representation
43           defined in RFC 2253 instead of the default OpenSSL oneline format.
44
45       -all
46           Display the text representation of the entire certificate in
47           addition to any other facts requested by command-line options. This
48           is the default if no fact-specific command-line options are used.
49
50       -subject, -s
51           Display the subject name of the X.509 certificate.
52
53       -issuer, -i
54           Display the issuer name of the X.509 certificate.
55
56       -issuerhash, -ih
57           Display the default hash of the issuer name of the X.509
58           certificate. This can be used to locate which CA certificate in the
59           trusted certificate directory issued the certificate being
60           inspected.
61
62       -startdate, -sd
63           Display a string representation of the date and time when the
64           certificate is valid from. This is displayed in the format used by
65           the OpenSSL x509 command.
66
67       -enddate, -ed
68           Display a string representation of the date and time when the
69           certificate is valid until. This is displayed in the format used by
70           the OpenSSL x509 command.
71
