grid-cert-info(1)


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

   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

ENVIRONMENT

   The following environment variables affect the execution of
   grid-cert-info:
