What is MD5, what is SHA-1, and how to verify these hashes. There is a single ISO document MD5,SHA-1 interrogation is not the original question, here, to do a final explanation of the above problems.
Let's take a look at some basic knowledge about
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

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
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
Today's theme is fountain code, or called "No rate Code". Fountain code is the method of converting some data, such as a file, into a valid arbitrary number of encoding packets, so that you can recover the source data as long as you receive a subset
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
ASP. NET has no magic-encryption and decryption of ASP. NET Identity, and identity encryption and decryption
The previous article introduced how to use Identity in ASP. net mvc to Implement User Registration, logon, and authentication. These
First, the basic knowledgeSymmetric encryption:The encryption and decryption parties use the same key to solve the data confidentiality, but the way the key is passed to the other party is not easy to implement;Public Key cryptography:Keys are
