Ssl vpn Definition
The development of ssl vpn is a supplement to the existing SSL applications. It increases the access control and security level and capability of the company.
Ssl vpn also helps enterprises that use remote access to the application system to reduce their security. In terms of attributes, dialing ensu
Introduction
The current version of SSLv3 is version 3.1, also known as TLS. It provides a mechanism for secure data transmission over the network. It is said to meet all security needs, such as your bank account management.
But here I will tell you that this is actually impossible.
In this article, I will first introduce SSL, which is very important. However, we will not introduce deep issues such as how

The word "trigger" has long been heard (the first is in the database video of Geng's aunt), after watching the video, the understanding of things such as: triggers, stored procedures, transactions, logs and so on no detailed to consult, there is no
This article mainly introduces a variety of different SSL configurations for MySQL, a very good article, and very practical. if you need it, you can refer to the post in this blog, I will describe different SSL configuration methods for using the MySQL database.
What does SSL give you?
You can use the replication feature of MySQL over the Internet or connect to
High-risk vulnerabilities exposed by SSL 3.0
On April 9, October 15, 2014, Google researchers announced a very serious vulnerability in the SSL 3.0 protocol, which can be used by hackers to intercept encrypted data transmitted between browsers and servers, such as online banking accounts, email accounts, and personal privacy. The SSL 3.0 vulnerability allows atta
1. About OpenSSLThe OpenSSL project is a collaborative development of a robust, commercial-grade, full-featured, open-source toolkit that implements Secure Sockets Layer (SSL v2/v3) and Transport Layer Security (TLS v1) protocols as well as a fully-powerful universal cryptographic library.2. Using SSL for Secure IOUsing SSL for Secure IO is not very different fro
Detailed tutorial on MySQL master-slave Replication Based on the SSL protocol,
When mysql is replicated across the Internet, others can steal the mysql replication information, which is in plain text and therefore insecure. Here, the copied information is encrypted through ssl. When a customer wants to access the server without a fixed ip address, mysql must allow access from any address. The server and cli
SSL VPN principle
If you separate the two concepts of SSL and VPN, you should know what they mean, but as a new technology, how they are combined may not be well understood. From the academic and commercial point of view, because they represent a different meaning, so often be misinterpreted.
SSL (Secure Sockets Layer) protocol is a common protocol that guarant

Abstract: SSL uses data encryption, authentication, and message integrity verification mechanisms to provide security assurance for application-layer protocols based on TCP and other reliable connections. This section describes the background, security mechanism, working process, and typical networking applications of SSL.

Generally, FTP servers transmit data in plaintext mode, which is very secure and information is easily stolen. Even if it provides SSL encryption, it may not be enabled by default, for example, the commonly used Serv-u ftp Server (Serv-U ). To ensure data security in special environments, it is sometimes necessary to enable the SSL function. The following uses the Serv-U server as an example to describe how

Background introduction Recently in the "Cryptography and Cyber Security" related books, this article is mainly about the famous Network security protocol SSL. Before beginning the introduction of SSL, we will introduce a few cryptography concepts and related knowledge. 1. Cryptography Related Concepts
Cryptography (Cryptography): The goal is to achieve security by encoding the information so th
The following is a Java certificate: HTTPS and SSL application notes test. I hope this article will help you.
When a connection is obtained, like a normal browser, the server certificate is still verified to be trusted (issued by an authority or signed by an authority). If the server certificate is untrusted, the default implementation will be problematic. Generally, errors are often reported when java accesses the

Currently, many websites or services are implemented based on SSL and can be accessed only after certificates are downloaded and installed. If it can provide download, of course there are any problems.
However, if you do not have permission to download and it is not a CA certificate, it is only a self-Signed server certificate. Only know its port and address. If you forcibly access it through a program, you may get the following error:
javax.net.ssl.
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 customer certificate. Generally, the server certificate and customer certificate are in a hierarchical relationship. The root certificate and
