%tldr on Mac

  • Get a certificate signed by a CA: click here for a free one,
  • open the file,
  • delete securely the file,
  • use Mail instead of online gmail.
  • ???
  • Profit

I've (re)discovered how to become S/MIME compliant. I am now suprised how easy it was. Some years ago it was far more difficult. Now I'm able to sign and encrypt my emails.

Why is it important?

Signing: it tell the other with an aboslute certitude the writer of the mail is you or at least used your computer.

Encrypt: because sometimes you need to be 100% sure a conversation remains private.

How to proceed?

  • Get a certificate signed by a CA: click here to get a free one,
  • open the file,
  • empty your trash, put the file in the trash, secure empty trash,
  • use Mail instead of online gmail. Now you should see these icons: blogimage("sign_icon.png","Sign icon")

n.b.: if you use gmail, you and work not alway with a Mac, you should consider to try the gmail S/MIME firefox addon.
