SSL protocol was first published by the Netscape Internet data security transmission protocol, the primary objective is to provide a secret between the two communication and reliable connection. The agreement consists of two layers, the bottom is based on a reliable transport protocol (for example: TCP) on the SSL record layer, used to package high-level agreement. SSL handshake protocol to allow servers and clients to transfer data at the beginning before the particular encryption algorithm through mutual authentication. SSL advanced is that it is a separate application protocol, and other higher-level protocols can be built on the SSL protocol. Check and reply.

SET is IBM, international organizations, credit card (VISA / MasterCard) and related companies jointly develop electronic transactions for network security protocols, which used the RSA public key encryption security, with data confidentiality, data integrity, data sources identifiability and non-repudiation, is used to protect consumers in the Internet card payment transactions, security standards. SET 1.0 version was officially come out in June 1997. Now, SET has become internationally recognized e-commerce transactions in the Internet security standard.

PGP is a public key encryption program, with the encryption method is different PGP public key encrypted message can only be decrypted using the private key. In traditional encryption methods, usually both an encryption key can decrypt. Then transfer the data before the start, how to channel through a secure transmission key. Using the PGP public key encryption, public key you can widely, and safely keep it private. Since only you have the private key, so anyone can use your public key encryption message addressed to you, without fear of information to be tapped. Check and reply.

At present, most of the Web Server and Browser most of the data to support SSL encrypted transfer protocol. Therefore, we can use this function, will be part of the confidential nature of the web page set in the encrypted transmission mode, so you can avoid the transmission of information in the network tapped by others.

PGP is a software encryption program, users can use it to create secure communication link information and communication security. PGP public key encryption protocol has become the worldwide information technology and the fact that safety standards. Because everyone can see its source code, so find out faults and vulnerabilities, all faults and flaws are corrected after the discovery.
