Subject: Re: Digital Certificate Expiration

Doug,

I wrote a command called CHKCERT that you can run to check when a
certificate will be expired.  For example, you might do this:

      CHKCERT HOST(www.klements.com) PORT(443) DAYS(7)

It will connect to www.klements.com and check that the SSL certificate
will be good for at least 7 more days.  If not, it'll send back an
*ESCAPE message.

That means you can write a CL program that runs this command and do
something like this:

PGM

    CHKCERT    HOST(www.klements.com) PORT(443) DAYS(7)
    MONMSG CPF0000 EXEC(DO)
        SNDMSG MSG('WWW.KLEMENTS.COM:443 WILL BE EXPIRED!') +
               TOUSR(KLEMSCOT)
    ENDDO

ENDDO

(You could change the SNDMSG to SNDDST if you prefer to send e-mail,
etc.) Then you could configure your job scheduler to run that program
every morning (for example) so that you'd have a week's notice if a
certificate is going to expire.  If you forgot to replace it, you'd get
another message the next day, etc.

This CHKCERT tool was written for an article entitled "How to Check if
SSL Certificates Are Expired" that I published in the Club Tech iSeries
Programming Tips newsletter.  If you have a Pro subscription to
