SYNOPSIS

grid-cert-info -help | -usage | -version | -versions

grid-cert-info OPTIONS

DESCRIPTION

The grid-cert-info program displays information contained within a certificate file. By default it shows a text representation of the entire certificate. Specific facts about the certificate can be shown instead by using command-line options. If any of those options are used, then the default display is suppressed. This can be added to the output by using the -all command-line option.

If multiple display options are included on the command-line, the facts related to those will be displayed on separate lines in the order that they occur. If an option is specified multiple time, that fact will be displayed multiple times.

OPTIONS

The full set of command-line options to grid-cert-info are:

-help, -usage

Display the command-line options to grid-cert-info and exit.

-version, -versions

Display the version number of the grid-cert-info command. The second form includes more details.

-file CERTIFICATE-FILE

Display information about the first certificate contained in the file named by CERTIFICATE-FILE instead of the default user certificate.

-rfc2253

Display X.509 distinguished names using the string representation defined in RFC 2253 instead of the default OpenSSL oneline format.

-all

Display the text representation of the entire certificate in addition to any other facts requested by command-line options. This is the default if no fact-specific command-line options are used.

-subject, -s

Display the subject name of the X.509 certificate.

-issuer, -i

Display the issuer name of the X.509 certificate.

-issuerhash, -ih

Display the default hash of the issuer name of the X.509 certificate. This can be used to locate which CA certificate in the trusted certificate directory issued the certificate being inspected.

-startdate, -sd

Display a string representation of the date and time when the certificate is valid from. This is displayed in the format used by the OpenSSL x509 command.

-enddate, -ed
