3. What is Encryption? The process of transforming clear text into coded, unintelligible text for security reasons. It’s used to help make transmissions more secure across networks and between users and Web sites.

4. A key is a number used to encrypt the data The encryption algorithm applies the key to the original message to produce the coded message. In symmetric encryption, the same key is used to encode and to decode. With asymmetric encryption, different keys are used; one key encodes the message, and the other key decodes the message. Symmetric encryption is simpler and much faster than asymmetric encryption.

5. Public key/private key is a special version of asymmetric encryption mainly used on the Internet.

6. Public key/ private key The public key encodes a message and is exchanged among users The private key decodes a message but is never exchanged among users.

7. Secure communication HTTPS is the most secure protocol used on the Internet. Secure Socket Layer (SSL), also known as Transport Layer Security (TLS), combines public key/private key with symmetric encryption to establish a secure exchange of data on a Web site. Web sites using this type of security will have https:// at the beginning of the URL.
