1. hash coding
2. Public key encryption (asymmetric encryption)
3. Private key encryption (symmetric encryption)

1. Secure Sockets Layer (SSL)
2. Secure HTTP (S-HTTP)
3. Virtual Private Networks (VPN)

Secure Sockets Layer (SSL)

SSL is one of the most popular of safe data transfer. First, the client establishes a connection to the server communication of basic information about the level of security, digital certificates, public key encryption, etc. Next, the customer should contact the appropriate certification authority (CA) to verify the authenticity of the digital certificate and the server. After authentication, a private session key is generated. This will provide faster processing on the client and server. After the session ends, the session key is discarded. Read More
