sha 2 algorithm explained

Exploring the principle and programming implementation of the SHA-1 algorithm in Redis source codeGuide The SHA-1 algorithm is short for the first generation of "Security Hash algorithm", and is essentially a Hash algorithm. SHA standards are mainly

Bitcoin's popularity in recent years has led to a study of blockchain technology. Of course, we do not discuss the blockchain technology itself, but discuss the application of the SHA algorithm in the blockchain. We have already explained the SHA

In the previous article we analyzed the principle of Sha, and took SHA1 as an example to implement the relevant algorithm, in this one we will further analyze SHA2 and realize it.1 , SHA Brief IntroductionAs we have already explained in the previous

Technology sharing-reinterpreting the Padding Oracle attack in CBC (how to break through HTTPS ?)     Why is it another explanation? Currently, the introduction of the Padding Oracle attack is based on this foreign language. However, this article

By analyzing the details of the TLS handshake process, we find that HTTPS increases multiple RTT network transfer times over HTTP, increasing the service-side overhead and slowing down the client response time. Therefore, performance optimization is

When you enter the URL at the beginning of HTTPS in the address bar of the browser, there is a lot of communication between the browser and the server within the next hundreds of milliseconds. Infoq's article has a very detailed description of this.

First, briefMAC (message authentication code, messaging authentication Code algorithm) is a key hash function algorithm that is compatible with the features of the MD and SHA algorithms, and adds a key on this basis. So Mac algorithms are often

Encryption algorithm behind SSL certificate (HTTPS)Before we introduced how SSL works, we learned that when you enter the URL at the beginning of HTTPS in the address bar of the browser, there will be a lot of communication between the browser and

Before we introduced how SSL works, we learned that when you enter the URL at the beginning of HTTPS in the address bar of the browser, there will be a lot of communication between the browser and the server within the next hundreds of milliseconds.

Topic One: Why is HTTPS safe1. Why is HTTP not secure?The HTTP protocol belongs to the plaintext transmission protocol, the interaction process and data transmission are not encrypted, the communication parties have not carried out any
