NAME

       grid-cert-info - Display information about a certificate

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
           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

           % grid-cert-info -sd -ed

           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

           CN=Joe User,DC=grid,DC=example,DC=org
