How does Email Encryption work?

Email encryption makes your messages unreadable to anyone other than the intended recipient to preserve confidentiality. It works on the principles of public key infrastructure, or PKI.

The concept revolves around two keys: public and private. The public key, which is stored on a key server, is accessible to everyone and is used to encrypt the messages on the sender’s end. The corresponding private key, which should be stored in a separate location, is used to decrypt the message on the receiver’s end.
