Email encryption can rely on public-key cryptography, in which users can each publish a public key that others can use to encrypt messages to them, while keeping secret a private key they can use to decrypt such messages or to digitally encrypt and sign messages they send.mail encryption is encryption of email messages to protect the content from being read by other entities than the intended recipients. Email encryption may also include authentication. Email is prone to disclosure of information.

However, decryption keys (private keys) are secret. This way only the intended receiver can decrypt the message.
