grid-cert-info - Display information about a certificate


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

grid-cert-info OPTIONS


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.

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

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

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.


Display the validity times for the default certificate

Aug 31 12:33:47 2009 GMT
