With the increasing popularity of e-commerce and e-government, problems such as theft and tampering of important data and files during transmission, network fraud, and network attacks also emerge, only by establishing a network security assurance system can online activities be improved. The CA technology is the core technology to ensure network security. About ca 1. What is

He just learned how to build a private CA through openssl last week and spent some time writing this script on Saturday. After that, he went to renew DNS, if you have any bugs, please forgive me. This script is purely an exercise for practicing openssl, awk, sed, and other knowledge points. First,

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.
