1. Terminology interpretation: The SHA1 algorithm requires a series of bitwise operations, the following describes the symbolic representation of the bit operations: Xor different or A xor B Or or A or B And with A and B Not is not A >n (n is

 Introduction I mentioned in cocos2d-x study note 16: record storage 1: CCUserDefault all kinds of defects of CCUserDefalut archiving, one of which is plaintext storage, players can directly modify the archive. This article describes how to use the

MAC (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 called HMAC

This paper mainly describes the process of computing the Information digest using the SHA1 algorithm.Security System (0)--encryption and decryption algorithm, message digest, message authentication technology, digital signature and public key

C # obtain the MD5 and SHA1 files, When I first started learning programming, I always wanted to write some small software gadgets. This is the typical file MD5 verification, and a SHA1 is added by the way. When downloading something on the Internet,

First, let's introduce the concept of MD5 and SHA1.MD5The full name of MD5 is message-digest algorithm 5 (Information-Digest algorithm). 128-bit length. At present, MD5 is an irreversible algorithm.It has high security. It corresponds to any string

PHP Cryptographic function-sha1 () function Encryption First of all, let's introduce what is SHA1? SHA is the full name: Secure Hash Algorithm (secure hashing algorithm) is mainly applied to digital signature (digital Signature standard DSS) in the
