SSL protocol and digital certificate principles 1st Floor Handshake and communication over the SSL protocolTo better understand and understand the SSL protocol, we will introduce the handshake protocol of the SSL protocol. SSL uses both public key encryption and symmetric encryption. Although symmetric encryption is faster than public key encryption, public key encryption provides better identity authentication. The SSL handshake protocol

After you enable Apache Mod_ssl, you need a certificate to function properly. Wrote a script to manipulate it. The first thing to make sure is that there are OpenSSL on the machine. Copy Code code as follows: #!/bin/sh # # The root directory for SSL certificate output.ssloutputroot= "/etc/apache_ssl"If [$#-eq 1]; ThenSsloutputroot=$1Fiif [!-D ${ssloutputroot}]; ThenMkdir-p ${ssloutputroot}Fi

For more information, see the requirements at the end of the article. In our series of articles on Java EE security, we have also described in detail how to create SSL connections and certificates in Java EE applications. As mentioned in the previous article, SSL (Secure Sockets Layer, Secure Sockets Layer)/TLS (Transport Layer Security, Tr

How to clear CNNIC Certificate Clear Windows certificates (applicable to IE, Chrome, and Safari) To use IE, Chrome, or Safari in Windows, perform the following steps: 1.

First, you need to understand some basic concepts before installing 1. Certificates used by SSL can be self-generated or signed by a commercial ca such as Verisign or thawte. 2. Certificate concept: First, you must have a root certificate, and then use the root certificate to issue the server certificate and custom

One of the things faced by many network engineers is the maintenance and update of SSL certificates. For the author, SSL certificates are mainly used for VPN deployment, but there are also many network devices that need certificates to encrypt client-to-server communication. Every time I claim that I need a certificate, everyone will become speechless, and the certificate may be a bit scary for most people.

After the IOS development environment is changed, re-create the Provisioning Profile certificate. I changed my MACOs and tried Provisioning Profile certificate again. Apple's certificate was complicated and complicated. Every time I made it, it was quite troublesome, And the Provisioning Profile certificate was bound t

The concepts related to certificates are really tricky because they haven't been exposed to certificate encryption before, because there's a whole new term coming up that looks like something else in another field, not something that we're familiar with in the programming world, at least personally, and I don't know much about it for a long time. The purpose of writing this article is to clarify these concepts, to understand their meaning and relevanc

Certificate formats-X.509, der and PEMPart: 1 2 3Certificate standard and File encodings seem to be confusing. I wrote down some notes about: What is X.509 certificate standard?

Before learning about the multi-domain wildcard SSL Certificate, we will first introduce the multi-domain certificate, also known as San certificate or UCC certificate, multi-domain certificates are described as follows:Multi-domain San/ucc ssl Certificate San

first, about the certificateDigital certificate is a kind of authentication mechanism. Simply put, it represents a security flag issued by an authoritative authority.OriginIn the past, traditional Web sites used HTTP protocol for data transmission, all the data used in almost plain text, it is easy to happen privacy leaks. In order to solve the security problem, we began to consider the use of encryption and decryption scheme, thus the birth of public

The overview is based on this tutorial. Http://st.appcan.cn/dev/dev_iosdom.html Due to Apple's mechanism, the installation of applications on a non-jailbreak machine must be done through the official App Store, developers can upload the App store after the app has been developed, and also need to pass the auditing process. Appcan can not only achieve cross-platform development, but also support the upload of IPA package to the App Store. This article describes how to compile the IPA package onl

[Slightly abridged] In order to achieve the popularity of the effect, I will try to use the more obvious, non-technical language to clear.★ First to say a popular exampleConsidering the knowledge of the certificate system is more dull and obscure.
