Google G Suite - Secure E-mail
Google started support for hosted S/MIME with the start of 2017, for their Enterprise version of G suite. This feature allows for sending and receiving encrypted email, with the use of Secure/Multipurpose Internet Mail Extensions (S/MIME) certificates. To make use of this feature, your certificate has to be uploaded to your G Suite account. To do so, you need to have your certificate available in a Public-Key Cryptography Standards (PKCS) #12 format, which contains both your certificate and private key. Creating the PKCS#12 (PFX) export is explained in full in our manual on Installation Code Signing Certificate or Client Certificate
