S/MIME ( Secure/Multipurpose Internet Mail Extensions) is a standard for public key encryption and signing of MIME data (MIME data being your emails). One is S/MIME, the other is PGP. This article will cover S/MIME, in which I’ll explain what it is and how to implement it (get ready for a lot of screenshots). Luckily, there are ways to bolt-on encryption to an existing email address! You can continue to use the email provider that you’ve been using all along and choose when to sign, encrypt or both sign and encrypt your outgoing emails. You likely end up with two or more email addresses to keep track of, along with other addresses that can collect spam.

But what if you already have an email address that’s been in use for years? Switching to another email address can be a real pain and old email addresses tend to stay active, just in case you forgot to tell someone you made the switch. Previously, I wrote about secure email providers - what to look out for and some suggestions of email providers you should consider trying.
