Computer Associates International, Inc (CA) recently announced that it won the best application/Management System Award at the Linux World China 2004 Conference. This shows that CA has once again affirmed its efforts to promote the development of Linux and open source communities. With the development and maturity of Linux, more and more enterprises begin to apply open-source software.

encrypts the communication between the browser and the server. The main differences between HTTPS and HTTP are the following four points: The HTTPS protocol requires a certificate to be applied to the CA, and the general free certificate is very small and requires a fee. HTTP is a Hypertext Transfer Protocol, the information is plaintext transmission, HTTPS is a secure SSL encryption transport protocol. HTTP and HTTPS use a co

Types of data encryption and the creation and application of CA certificates1. Data transmission over the Internet must be guaranteed by the following 3-point features:Privacy: Encryption of dataIntegrity: The data transfer process has not been modified.Authentication: Confirm the identity of the other, prevent the man-in-the-middle camouflage attack2. Privacy: Data encryption should use symmetric encryption, features fastThe representation algorithm

CA certificates are widely used in digital signatures, and because Windows supports RSA algorithms well, many third-party applications under the Windows platform support the application of cryptography for RSA algorithm certificates. Recently, the opportunity to take advantage of project summary, especially in Windows under the common CA Certificate digital signature application. The program is divided into
