What Is an Encrypted Email?

Email encryption is the process of hiding material so that only the intended receiver may view it. It needs authentication to be accessed, which helps to keep sensitive data safe. By encrypting your emails in this manner, you safeguard your data from hackers.

Asymmetric encryption, often known as public-key cryptography, is the most popular kind of encryption. It entails two distinct keys, one private and one public.

Your public key may be distributed to others so that they can encrypt communications for you. When a message arrives in your inbox, the private key is utilized to decode it. The private key must be kept secure since it allows your communications to be unlocked and read.

Symmetric encryption, often known as secret-key cryptography, is a safe and simple encryption technology that uses a single cryptographic key. To unlock the communication using this sort of encryption, you must provide the receiver a key.
