                      [-issuerhash] | [-ih]

                      [-endate] | [-ed]

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.

       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
           certifcate 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, -dd
           Display a string representation of the date and time when the certificate is valid
           until. This is displayed in the format used by the OpenSSL x509 command.

EXAMPLES

       Display the validity times for the default certificate

           % grid-cert-info -sd -ed
           Aug 31 12:33:47 2009 GMT
           Aug 31 12:33:47 2010 GMT

       Display the same information about a different certificate specified on the command-line

           % grid-cert-info -sd -ed -f /etc/grid-security/hostcert.pem
           Jan 21 12:24:48 2003 GMT
           Jul 15 11:30:57 2020 GMT

       Display the subject of a certificate in both the default and the RFC 2253 forms.

           % grid-cert-info -subject
           /DC=org/DC=example/DC=grid/CN=Joe User
           % grid-cert-info -subject -rfc2253
           CN=Joe User,DC=grid,DC=example,DC=org
