other system's user name and password calculation, import ucenter uc_members table, to achieve user migration. For example, if the original system uses an algorithm such as MD5 (password) to save the password, then the program randomly generated salt, and then calculate the cumulative MD5, so it is easy to calculate the user in the Ucenter user password hash value, so as to achieve seamless user migration. However, if the original system is using MD5 (Password+salt) to save the password, it wil

This will use the suffix array. Note: Because it is annular, it is necessary to first copy the multiplication string, get the new string, and giveNew StringThe first half of the sequence, and then output each in the multiplication aft

This article introduces two methods of cipher encryption, these two are very common can be found at random Baidu. 1. Morse Code; Say password encryption has to be put to the method. It's a classic. First of all, tell him the comparison table, directly above the picture. The core idea is to replace the plaintext cipher and replace the characters with the. two symbols; 2, fence password; The so-

In cryptography, Caesar's code (or Caesar's encryption, Caesar's transformation) is one of the simplest and most widely known cryptographic techniques. It is a technique for replacing encryption, in which all letters in plaintext are replaced by a fixed number of Cheng Mi-wen (or forward) after the alphabet is offset. For example, when the offset is 3, all the letters A will be replaced with D,B into E, and so on. This method of encryption was named after Caesar, who had used this method to comm
