A Very Short PKI Consultant Story
This web site's purpose is not to tell you about myself... rather the work I do.  I've published a few items which inform you a little about a 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: david@wozny.org.  I've also worked for no pay as a volunteer 'IT Buddy', so you could possibly engage me for nothing!



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 GCHQ.gov.uk.  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 green padlock in your browser.  Without a green padlock, there'd be no online banking or secure login to email... or whatever!
