PHP Learning--php Encryption, PHP learning--php encryption There are several types of encryption in PHP: 1. MD5 Encryption String MD5 (string $str [, bool $raw _output = false]) Parameters STR--the original string. Raw_output--If the optional

/*** Encrypted string decryption is valid within a specified time* @param [Type] $string Clear text string* @param string $operation decrypted value is decode and other values are encrypted* @param string $key encryption key* @param integer $expiry

The basis of this algorithm: the character A B,a^b=c,c^b=a, that is, two times the XOR operation can get the original character. The implementation code is as follows:/** * @desc encryption * @param string $STR string to be encrypted * @param string

Any length of input, fixed-length output, the output is a hash value, this conversion is a compression mapping, that is, the space of the hash value is much smaller than the input space,Different inputs may be hashed to the same output, and cannot
