What is ca?
Ca is short for Certificate Authority. It is usually translated into an authentication authority or a certification center. It is mainly used to issue digital certificates to users. This digital certificate contains part of the user's identity information and the public key held b

In HTTPS learning note two, the concept of digital certificates has been clarified, composed and how the client validates the server-side certificate during the HTTPS connection process. This chapter describes how to use the OpenSSL library to create a key file, and to generate a root CA and issue a child certificate. Learn the main reference Official document: h
The term "digital certificate" is believed to have been heard by many people, but it is not understood that "EJBCA" may not have been heard by many peopleDigital certificate (Certificate), is the Internet communication process in the identification of the identity of the communication of a document, can be understood as "network ID", the main purpose is to verify
The company is to do it finance this piece, the security of the server or relatively pay attention to, recently there is a server electronic certificate expires immediately, need to renew the generation of electronic certificates. In order to avoid the risk to the production environment business, we need to set up a test environment to test the electronic certificate. The records are as follows:Environment:
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 trans
OpenSSL Toolkit is one of the implementation methods of SSL v2/V3 and TLS v1 protocols on Linux, and provides common encryption and decryption functions.
OpenSSLIt consists of three parts:
1:Libcrypto: an encrypted library mainly used to implement encryption and decryption.
2:Libssl: implements the SSL server-side function session Library
3:OpenSSL command line tool:/usr/bin/OpenSSL
This document only describes how to use the OpenSSL command to create a private
In a recent project, the establishment of the PKI system has not been completed before, so it was confused at the beginning. I slowly found out some results and shared them with you. I hope you can correct the incorrect information.
At present, the PKI system has become the key point of information security in an enterprise and is the pillar of information security. My project is based on Microsoft technology. The CA

Through the official seal, it can be proved that the letter of recommendation is actually issued by the corresponding company.Theoretically, everyone can find a certificate tool and make a certificate of their own. How to prevent the bad guys from making their own certificates and cheating? See the introduction of subsequent CAs. ◇ What is CA?The

Preface openSSL is a powerful encryption tool. many of us are already using openSSL to create RSA private key or certificate signature requests. However, you can use openSSL to test the computer. speed? You can also use it to encrypt files or messages. Openssl is a suite of open-source programs. it consists of three parts: libcryto, which has

Recently beans need to clean up the company's PKI server. Due to historical reasons, the company before the intranet built 2 enterprise root level of the CA server, the boss let me build a new, and then the previous 2 to dispose of. Microsoft's ad environment is allowed to build multiple PKI structures at the same time, but the result is that it is possible for the client to apply for a certificate at rando
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 signa
If the site is for intranet access, build the CA server to issue certificates, if it is for the Internet to access, or to buy SSL certificate is better, today to introduce themselves to build CA server issued a certificate to do encrypted Web site.192.168.10.187 CA Server192
