PGP/GPG

Here you can download a copy of the PGP Intro to Crypto documentation that originally came with Pretty Good Privacy by Phil Zimmermann.

PGP has been superseded by GPG

But details of the original PGP can be found via Phil Zimmermann's webpages.

I have several OpenPGP keys including an old RSA one which I used back in 1995 but it uses the patented IDEA algorithm later ones don't. My latest one was created with GPG with is compatible with OpenPGP, which is used by later versions of PGP and it's successors from Symantec. Please use my latest key. I have also lost private keys I made at some points.

I use Kmail which integrates with gpg, and use KGpg for key management. If you use MS Windows I advise you to try Thunderbird email client which one can integrate GPG into with Enigmail plugin. I have used OpenKeyChain with K9Mail on Android. If you just use webmail then there are various browser plugins that help, but these have tended to come and go in past, so best to look out for latest up to date regularly bug fixed one available.

If you want hide IP addresses used by you while web surfing use TOR ( https://tor.eff.org/ ) or try finding & using a Virtual Private Network service such as NordVPN or ipredator.

If you want to use encryption to the email address you already use on home computer get a copy of PGP or GPG and you can send encrypted mail to other PGP users like me using my public GPG key, once one has read the user guide and set it up it is quite straight forward to use.
