I heard that let's encrypt has already started public beta, so immediately began to try. Let's Encrypt is a new digital certification authority that automates the process of eliminating the complexity of creating and installing certificates, and provides free SSL/TLS certificates for websites. The following is the process of using Let's Encrypt: Get the client and execute --note that the Python version requires >=2.7git clone https://github.com/let

The default Fabric1.0.2 example is not based on TLS, but the Balance-transfer and e2e_cli examples are based on TLS, and in order to make the connection more secure and generic, the research supports the implementation of log monitoring based on TLS. The example/events/block-listener.go example in the Fabric1.0.2 source code produces the process of listening to t

Three Windows Server SSL/TLS security vulnerabilities and their remedy Not long ago, the simple use of SSL on Windows servers, or its successor TLS, were considered safe communication methods. But now the era has changed, and SSL and TLS have become corrupted. In the past few years, many serious security vulnerabilities that are worth your attention have been exp

This is a creation in Article, where the information may have evolved or changed. The Go programming language makes it easy-to-write and deploy servers offering HTTPS (HTTP + Transport Layer Security) to Clients. The crypto package in Go's standard library are easy-to-use and well Documented:it's an under-explored gem. Due to it's low-on-legacy implementation of modern standards and easy configurability, there are no reason to insert Apa Che or Nginx server to terminate

Can you introduce the problems found in the RC4 encryption algorithm recently? In this regard, what security risks do HTTPS network connections face? How should enterprises ensure that they are not attacked by this vulnerability? Michael Cobb:RC4 (Rivest password 4) was designed by Ron Rivest of RSA Security in 1987. Due to its speed and simplicity, this encryption algorithm has become the most widely used stream password. It is used in common protocols, including Wired Equivalent Security (WEP)

First, the roleHTTP communications that do not use SSL/TLS are non-encrypted traffic. All information is transmitted in plaintext, potentially three major risks.1, eavesdropping risk (eavesdropping): Third party can learn the content of the communication.2. Tamper risk (tampering): Third parties may modify the content of the communication.3. Impersonation risk (pretending): A third party may participate in the communication by impersonating another pe
