PGP Marks 30th Anniversary

Interesting that Phil does not prefer to really use pgp himself!

He writes:

"Note: I don't have a PGP client that runs on my iPhone, which is where I
process most of my email. This means you should send me plaintext email if you
want me to read it. (Yes, I know, I know.)"

How ironic.  :)
