Using SSL in the Web

SSL (Securesocketlayer) is a secure communication standard primarily used for the web, located between the transport layer and the application layer. Data is encrypted as it flows through it, again to TCP/IP, and the data from the TCP/IP into its first layer is decrypted, and it can verify the identity of both ends of the network connection, it provides a security mechanism to ensure that the HTTP transaction in the transmission is not monitored, forged and tampered with. SSL is now the de facto standard for securely transmitting data over the Internet, which is integrated into every common Web server and browser for sensitive information on online transactions that protects credit card numbers and stock trading details. Encryption of the Web system using SSL is inseparable from the generation of key pairs and the issuance of certificates, CA (Security Certification Center) to complete the issuance of certificates. The user can pay the CA to sign the certificate, when the user wants to generate a certificate request to pass to the CA, waiting for the issuing CA. If the user is for testing, you can create a CA and issue the certificate yourself by using the Certificate Server on Windows2000 or the OpenSSL on Linux. SSL enhances the security of the Web system. But there is a price to pay for this safety boost. SSL in the handshake process will consume a lot of computing resources, even in the normal data communication after the handshake, but also because of the complex encryption/decryption algorithm increased the burden of the system. SSL is a CPU-devouring, and it can be a major barrier to Web server performance, causing the Web site to respond as quickly as a snail. However, there is now an SSL accelerator to help E-commerce Web sites solve this problem, through the use of specialized equipment to handle the SSL protocol, so that the server CPU from the heavy encryption/decryption process freed. Therefore, given the impact of SSL on server performance criticality, it is advisable for Web sites that use SSL to configure specialized SSL acceleration devices.
