Why do I need to encrypt emails?
Before moving on to how to encrypt email, let us elaborate on why you should do it in the first place.
Emails primarily include lots of sensitive data. For instance, business emails may consist of everything from employees’ account credentials to consumers’ personal and non-personal data. Also, intra-business emails frequently include reports, event logs, salary details, financial information, and other lucrative data for cybercriminals.
Likewise, hospitals, labs, and medical facilities often include critical PHI data of patients as well.
Similarly, personal email users also share important information via emails, such as account credentials, phone numbers, addresses, and much more.
Many times, users even communicate about sensitive topics via emails that you may think of as unimportant for anyone. However, your government and surveillance authorities would be interested in that.
So, to protect all this data contained in your emails, the only viable solution is to apply email encryption.
However, such encryption won’t effectively protect you from targeted surveillance, such as NSA’s PRISM Program. But it will provide adequate security from data mining and data monetization by your ISP and other third parties.
How does email encryption work?
Email encryption also employs the usual encryption methodology. The process transforms the readable (plain text) emails into an unreadable (ciphertext) format.
Doing so ensures that your message remains protected during transit and that nobody else can read your message except your intended recipient.
