2. Today, all browsers in the market support SSL, and most of the secure communication are proceeded through this protocol. SSL works completely hidden for the users, who does not have to intervene in the protocol.
3. The only thing the user has to do is make sure on URL starts with https://instead of http:// where "s" obviously means secured.
4. SSL was renamed as TLS (Transport Layer Security) in 2001.
19.
Encryption technology is an effective information security protection. It is defined as converting a plaintext into meaningless ciphertext using encryption algorithm thus ensuring the confidentiality of the data. The encryption or decryption process use a key to encrypt or decrypt the data. At present two encryption technologies are widely used. They are symmetric key encryption system and an asymmetric key encryption system. Thre figure below shows the Data Encryption and Decryption process:
