When you want to add an extra layer of protection to your personal messages with or without files attached, you encrypt them. So, how to encrypt email? To make it easier for you, there are many different options out there available to anyone for encrypting email messages and they work very similarly as they use the same end-to-end encryption technology. When you encrypt an email, your email message is converted from its easily readable text form into unreadable, scrambled data that cannot be viewed by anyone except you the sender, and the intended recipient.

Whenever you send an encrypted email message, only you and the intended recipient have the required encryption key. The recipient of your encrypted email has the required private key and this private key always matched the encryption public key. With this key, encrypted messages are decrypted once they reach the intended recipient. Anyone else without the key required cannot view and read your email messages.

How Email Encryption Works?

Email encryption works very similar to encryption technologies that instant messaging apps for Android, iOS, and Windows devices use to let you send self destruct, encrypted text messages, photos, videos, and other files. Email encryption technologies protect the private, confidential content you share via email from being accessed and read by third parties, and anyone else who is not the intended recipient.

When looking into how to encrypt email, you are looking for end-to-end encryption-empowered services, tools, and features. These generally employ public-key cryptography. Public-key cryptography used in these services is a powerful encryption system that uses public and private keys and their generation depends on sophisticated cryptographic algorithms. While public keys can be distributed private keys are always kept safe and secure for effective privacy and security.

When you send an email using standard emailing options, these email messages are usually encrypted as they travel from you to the intended recipient or during their transmission. However, at the same time, these messages are stored in their plain text form so they are readable by your email provider or some third parties. When you send an encrypted email, that message is encrypted during transmission as well as on your and the recipient’s part so it cannot be viewed by third parties or other outsiders.

The best, the most secure email encryption technology is end-to-end encryption and this is what you are looking for when learning how to encrypt email. The data within encrypted emails is encrypted on your part and then decrypted as it reaches the intended recipient. This means it is unreadable to your email service providers such as Outlook or Gmail. There are several different email encryption protocols that popular services use including S/MIME, PGP (Pretty Good Privacy), and GPG (GNU Privacy Guard).
