PHP encryption and decryption string functions frequently used in programs The code is as follows: /********************************************************************* function Name: Encrypt function: Encrypt decryption string use method:

Some of the following PHP functions are the most commonly used project development functions of our IT power, these functions are used in more projects, and are more general. 1. Processing function of Request interface Copy Code code as

AES encryption algorithm-algorithm principle The AES algorithm is based on permutation and permutation operations. The arrangement is to reschedule the data, and the permutation is to replace one data unit with another. AES uses several different

It has always been thought that there are two bytes to record the length (a small length can also be recorded in a byte), so the problem was very boring at that time, but then some people in the group to explain, suddenly found that the original

String Intercept function A The code is as follows Copy Code function MyStr ($str, $str _len) {//Cut a certain length of string (string, cut length)if (strlen ($str) return $str;}else return Mysubstr ($str, 0, $str _len).

Sometimes in the project we need to use PHP to encrypt specific information, that is, through the encryption algorithm to generate an encrypted string, the encrypted string can be decrypted by decryption algorithm to facilitate the process of

Copy Code code as follows: function Syssubstr ($string, $length, $append = False) { if (strlen ($string) { return $string; } Else { $i = 0; while ($i { $stringTMP = substr ($string, $i, 1); if (Ord ($stringTMP) >=224) { $stringTMP =
