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.
Symmetric encryption cannot be used for signing, which is why a combination of algorithms is used. So, for example, the sender of a message would use the recipient's public key to encrypt a randomly generated session key -- used to encrypt the content of the actual message.
