Important matters:Generate your private key at the same time as the CSR file is generated, and if you lose the private key or forget the private key password, the certificate is issued to you and cannot be installed successfully! You must regenerate the private key and the CSR file and reissue the new certificate for free. To avoid this situation, be sure to back up the private key file and remember the pri

the subject of the certificate (that's oddly fitting isn' t it ?). In a web context that subject is the hostname. However it's not just hostnames that can be an alternative subject. Email is an option as is IP addresses.
The first step is to create a CSR (Certificate Signing Request) that contains the subject alternative names that you desire for your certificate. I will show how to do that using OpenSSL. you will likely need to modify the default Op

If you apply for https (do not use your own certificate, apply to CA), this must match the domain name; otherwise, a browser alarm will be triggered. After the generated csr file is signed by the CA, the server certificate sudo openssl req-new-key testcert is formed. key-out testcert.
Build your own CA to sign the certificate
This series of articles is divided into three parts: build your own certificate issuing service, generate a certificate request, and sign the generated certificate request through the self-built CA and finally apply it to the service,
This article describes how to use the CA Service in the previous article to sign the certificate.
This article assumes that you have read the first two articles and make sure the following paths are met:The private key o
and whether the digital signature of the ca is in the approval list. If both checks pass, the client and the server can easily start session key negotiation to determine which encryption algorithm will be used for subsequent communication content, and generate a session key that is only used for this communication. Then, the session key generated by the Protocol can be used to communicate with the algorithm secretly.

A digital certificate is a file digitally signed by the certificate authorization center that contains information about the public key owner and the public key. It is time-sensitive and valid only for a specific period of time.
There are two types of iOS certificates:Development Certificate)AndProduction certificate).

First, you must use RouterOS on the server computer through the command line to create a certificate (CSR) marked with a request, or you can use a new terminal window in WinBox.
Run the following command:

After Xcode7, Apple supports certificate-free debugging, but if you need to debug the push feature or need to publish the app, you'll need to use a paid developer account.Certificate configuration process, the online tutorials are many, but also very detailed, the control step by step, generally can be configured successfully.This article explores the mechanisms behind these steps and the goals that each step achieves.

Use of digital certificates can increase user confidence
The public key in the digital certificate can be paired with the private key of the server to realize the encryption and decryption during data transmission.
