First, the HTTPS service must be built with an HTTPS certificate. This certificate can be viewed as an application-level certificate. The reason for this is that the HTTPS certificate is generated based on the CA certificate. For official websites, CA certificates require a qualified third-party certification authority to apply for access. For some of our self-built small projects, you can use your own serv
Twobased onHTTPS replication for CA certificates ??????? I just looked at it. On the system disaster tolerance based on Kerberos and CA certificate (on) or in 2017-08-31, until now half a year passed, lazy cancer is too heavy, has not been updated, from today onwards will gradually update the beginning of the tutorial, I hope to have more friends to understand and learn Microsoft virtualization technology.
Charles Proxy, like Fiddler under Windows, can view HTTPS traffic, but when you check HTTPS requests using the CA certificate provided by Charles, the following error occurs on Firefox 35 Web page:Twitter.com uses a invalid security certificate. The certificate is not trusted because the issuer certificate has. (Error code:sec_error_expired_issuer_certificate)The reason is said to be this:

Objectivewith the rapid development of Internet, network communication has become the main way to transmit information. While the communication of data transmission is mostly Ming wen Transmission, in the network of this insecure environment, if there is no set of data encryption mechanism, will lead to sensitive information and important data leakage, causing immeasurable loss. and OpenSSL just made up for this shortcoming, what is OpenSSL? OpenSSL is a powerful set of cryptographic components

Often some enthusiastic netizens ask me about the use of the small CA system, here is a brief explanation:

Password Authentication protocol Although the hardware requirements are not as high as the Challenge Handshake protocol, however, in terms of security, it is still a distance from the challenge handshake agreement. The specific authentication protocol to be used, the user should be judged according
I. INTRODUCTION OpenSSL is an open-source encryption tool. in a Linux environment, we can use it to build a CA for certificate issuance. it can be used in an enterprise's internal encryption tool, the following is a powerful OpenSSL tool. in Linux, a CA is built to implement Certificate Management.
