Introduction to Hash method hash functions and the number of bits in various forms of hashing common hash function versions hash code download
Introduction Dilute functions by definition you can implement a pseudo-random number generator
MD5 is message digest algorithm 5 (Information AbstractAlgorithm(MD5) is a Hash technology that is widely used in encryption, decryption, Data signature, and data integrity verification. Any file, whether it is executableProgramImage files,
I. List of data encryption/coding algorithms common cryptographic or coding algorithms used to ensure security are as follows: 1, common key algorithm key algorithm is used to encrypt sensitive data, digest, signature and other information,
I. Integer Hash Functions
There are three common methods: Direct remainder method, Product Integer method, and square method. The three methods are discussed below. The following assumes that our keyword is that the capacity of the hash table is,

In the development of various application systems, often need to store user information, many places have to store user passwords, and the user password directly stored in the server is obviously unsafe, this article briefly introduces the work of
The example of this paper describes the Base64 encryption, MD5 encryption and SHA1 encryption implemented by JS. Share to everyone for your reference, specific as follows:
1, Base64 encryption
