A Short PKI Consultant Story
This web site's purpose is not to tell you about myself... rather some of the work I do.  I've published a few items which inform you a little about an IT security capability which I am supposedly skilled at - Public Key Infrastructure (PKI).

The web site is neither a curriculm vitae or resume - and I shan't publish one here.  However, I am an IT security consultant who is sometimes available to hire.  If you are interested in contacting me (or acquiring my CV) you could send an email enquiry to  I've also worked as a volunteer 'IT buddy', so I could possibly be engaged at zero charge!

Is PKI Still Relevant in the Mobile Device \ Cloud Era of the Internet?

Robert Hannigan, director of GCHQ until 2017, once shared his thoughts about PKI on  I extracted the following from the statement he made: “Almost every aspect of life online relies on PKI.”  Powerful stuff indeed!

​My 'Quote' :-)  Without PKI, there'd be no HTTPS.  Without HTTPS, there'd be no closed padlock in your browser address bar.  Without a padlock, there'd be no online banking or secure login to email... or whatever!
