NAME
       certwatch - generate SSL certificate expiry warnings

SYNOPSIS
       certwatch [OPTION...] filename

DESCRIPTION
       The certwatch program is used to issue warning mail when an SSL certificate is about to
       expire.

       The program has two modes of operation: normal mode and quiet mode. In normal mode, the
       certificate given by the filename argument is examined, and a warning email is issued to
       standard output if the certificate is outside its validity period, or approaching expiry.
       If the certificate cannot be found, or any errors occur whilst parsing the certificate,
       the certificate is ignored and no output is produced. In quiet mode, no output is given,
       but the exit status can still be used.

       The certificate can be specified by its nickname or by a path to the containing file.

OPTIONS
       --quiet, -q
	   Enable quiet mode; no output is produced whether the certificate is expired or not

       --period days, -p days
	   Specify the number of days within which an expiry warning will be produced; default is
	   30. Expiry warnings are always produced if, on the day of invocation, the certificate
	   is not yet valid, has already expired, or is due to expire either that day or the
	   following day.

       --address address, -a address
	   Specify the address used in the To field of the warning e-mail issued if quiet mode is
	   not enabled. The default is root.

       --directory cert-directory, -d cert-directory
	   Specify the database directory containing the certificate and key database files. The
	   default is yet to be determined.

DIAGNOSTICS
       The exit code indicates the state of the certificate:

       0
	   The certificate is outside its validity period, or approaching expiry

       1
	   The certificate is inside its validity period, or could not be parsed

NOTES
       The certwatch program is run daily by crond from the file /etc/cron.daily/certwatch to
       generate warning mail concerning the imminent expiry of SSL certificates configured for
       use in the Apache HTTP server. These warnings can be disabled by adding the line:
       NOCERTWATCH=yes to the file /etc/sysconfig/httpd. Additional options to pass to certwatch
       can be specified in that file in the CERTWATCH_OPTS environment variable.

FILES
       /etc/cron.daily/certwatch, /etc/sysconfig/httpd
