I had a question last year about security on Gmail, Google’s e-mail system. Previously, any mail you opened or sent was not sent securely, so it could be intercepted by a third party. In 2008, Gmail added encryption for Gmail, but it wasn’t the default setting, so most folks were still sending mail unsecured.
The good news is that after China hacked many Google Gmail accounts earlier this month, Google decided that the benefits of keeping mail secure was more important than any slow down in opening and sending mail. So Gmail now has encryption turned on by default. If you didn’t have it turned on before, you might notice the service is slightly slower than before, but it’s worth it to keep your mail safe.
