What Is Secure Email:
Secure Email is a safe, efficient alternative to regular email, fax, and post. When you hit the send button on your secure email, the information contained in it is encrypted, so it can only be read by your intended recipient. Unlike regular emails, that can easily be read by anyone.

How Does Secure Email Work:
Secure Email allows you to encrypt the contents of your email when you send it. This encryption ensures that the email, if intercepted, will not be readable. Once the email reaches its destination it will be decrypted so that the intended recipient can read it. There are two types of encryption.

• Asymmetric Encryption - this system requires a user to use two alphanumeric keys, one private and one public. Your public key is avaliable to anyone. This allows an outside sender to automatically generate a code using a defined set of explicit instructions. When someone sends you an encrypted email, you can use your public key to translate the message. Only you can decipher the code, using a private key. To generate a public key, you will need to install a security program and set up and verify a pass phrase.
• Symmetric Encryption - also known as single key or private key encryption, sharing one key between a sender and receiver. That means you and the receiver need to decide on a password before sending the encrypted message. Coding and decoding runs faster than asymmetric encryption. However, this can leave you email message more vulnerable to hackers because it is a shared key between two people.
