This example describes how to implement cookie encryption in php. Share it with you for your reference. The specific implementation method is as follows:

The code is as follows: <? Php
Class Cookie
{
/**
* Decrypt the encrypted cookie.
*
* @ Param string $ encryptedText
* @ Return string
*/
Private static function _ decrypt ($ encryptedText)
{
$ Key = Config: get ('secret _ key ');
$ CryptText = base64_decode ($ encryptedText );
$ IvSize = mcrypt_get_iv_size (MCRYPT_RIJNDAEL_256, MCRYPT_MODE_ECB );
$ Iv = mcrypt_create_iv ($ ivSize, MCRYPT_RAND );
$ DecryptText = mcrypt_decrypt (MCRYPT_RIJNDAEL_256, $ key, $ cryptText, MCRYPT_MODE_ECB, $ iv );
Return trim ($ decryptText );
}
/**
* Encryption cookie
*
* @ Param string $ plainText
* @ Return string
*/
Private static function _ encrypt ($ plainText)
{
$ Key = Config: get ('secret _ key ');
$ IvSize = mcrypt_get_iv_size (MCRYPT_RIJNDAEL_256, MCRYPT_MODE_ECB );
$ Iv = mcrypt_create_iv ($ ivSize, MCRYPT_RAND );
$ EncryptText = mcrypt_encrypt (MCRYPT_RIJNDAEL_256, $ key, $ plainText, MCRYPT_MODE_ECB, $ iv );
Return trim (base64_encode ($ encryptText ));
}
/**
* Delete a cookie
*
* @ Param array $ args
* @ Return boolean
*/
Public static function del ($ args)
{
$ Name = $ args ['name'];
$ Domain = isset ($ args ['domain '])? $ Args ['domain ']: null;
Return isset ($ _ COOKIE [$ name])? Setcookie ($ name, '', time ()-86400, '/', $ domain): true;
}
/**
* Obtain the value of the specified cookie.
*
* @ Param string $ name
*/
Public static function get ($ name)
{
Return isset ($ _ COOKIE [$ name])? Self: _ decrypt ($ _ COOKIE [$ name]): null;
}
/**
* Set cookie
*
* @ Param array $ args
* @ Return boolean
*/
Public static function set ($ args)
{
$ Name = $ args ['name'];
$ Value = self: _ encrypt ($ args ['value']);
$ Expire = isset ($ args ['expire '])? $ Args ['expire ']: null;
$ Path = isset ($ args ['path'])? $ Args ['path']: '/';
$ Domain = isset ($ args ['domain '])? $ Args ['domain ']: null;
$ Secure = isset ($ args ['Secure '])? $ Args ['Secure ']: 0;
Return setcookie ($ name, $ value, $ expire, $ path, $ domain, $ secure );
}
}
