First, generate certificate signing Request (CSR) in IIS Personal understanding: The generation of a CSR is the creation of a "private/public key pair" from which the public key is extracted. 1. Open IIS Manager, select Server certificates in the root node, click the Create certificate Request on the right ..., and then fill in the corresponding distinguished Name Properties (see figure below). Common name to fill in the domain name (if used for all level two domain name, fill *. domain nam

Small black daily tossing-quick creation of shell scripts for private CA Tom started to make new things again. 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,

Use openssl to build a Root CA in CentOS 6 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. Ii. Construction 1. Fi

Build your own certificate issuing service (CA) This series of articles is divided into three parts. It mainly introduces how to build your own certificate issuing service, generate certificate requests, and sign the generated certificate request through the self-built CA and finally apply it to the service. By building your own certificate service, you can sign your own application certificate without buyi

CA has conditional receiving system and scrambling and encrypting two parts. Scrambling is an image, sound, and data stream under the control of a CW (or a key) in a way that makes it impossible to watch, and encryption is the process of protecting the key. The encrypted key must be transmitted to the client along with the scrambling signal. On the client side, the solution CW is decrypted with the smart card, and the scrambling signal is disturbed by
