Online Privacy

End-to-End Encryption

Most (if not all) email service providers use TLS (transport layer protocol) as a means to protect emails from being read by outside parties, but TLS still allows the email service provider, such as Google or Yahoo, to scan your emails. In fact, many email service providers admit in their privacy policies that they retain the right to collect

  • your personal information,
  • information from your emails, and
  • information about your device (which is used for tracking purposes).

Hackers and even government agencies can also find ways to scan, read, and copy your emails.

The best way to protect your email is through a process called end-to-end encryption. End-to-end encryption is a process that only allows the sender and receiver of an email to read its content. The email service provider cannot scan or read an email has been sent using end-to-end encryption. End-to-end encryption does not, however, encrypt the sender and receiver's email addresses or the email subject line from being scanned.
