I have just installed GnuPG (GNU Privacy Guard) which is basically an open source version of PGP (Pretty Good Privacy) which was free many years ago but is so no longer. You can download my public key using the link below. The link above to GnuPG has a link to a Windows version that includes a plugin for Outlook and there is an extension for Mozilla Thunderbird at this link that will utilize the GnuPG key system.
Why do this? Well there are several reason, but one is to ensure that email from me really did in fact come from me. Not that I that I’m some kind of big shot that needs this level of “insurance” but I think it’s good common practice in general and this method (or something similar) should be utilized more often by the general public and major companies (especially those in the financal busines). It also allows me to encrypt messages as I need to and basically keep my privacy.
So if you plan on emailing me, be sure to grab my public key (using the link below) and add it to your keyring.
