Summary of research on hash table and hash functionWith the increasing of information level, the data has been replaced computing as the center of Information Computing, the demand for storage has been increasing the volume of explosive growth trend,

A one-way hash function algorithm, also called a hash (hash) algorithm, is a function that compresses a message of any length to a fixed length (The Message digest) (the process is irreversible). The hash function can be used for digital signature,

It is of great significance to study the encryption and decryption of MySQL database in the course of network attack and defense. Imagine that once you have access to the site's permissions, if you can get the data stored in MySQL, through the
