Email Encryption Software allows the disguising of content within email messages so that they cannot be read by anyone apart from the intended recipient. Emails are typically encrypted and then decrypted by means of a digital signature mechanism that uses public and private keys. The public key is shared with everyone while the private key is kept private.

Encryption also usually includes authentication where the user is obliged to prove his or her identity by using a username and password combination in order to get access. More recently biometrics (fingerprints or eye retina recognition) is used instead of username and password, making it more difficult for hackers to break into computer systems.
