php/js/linux: js加密（rsa公钥加密） php解密（rsa私钥解密）
一：
js rsa 插件
https://github.com/UFO0001/WX_RSA
或者：
https://files.cnblogs.com/files/achengmu/WX_RSA-master.zip
二:
代码所在的服务器生成：private_key/public_key 两个文件
php代码如下：
<?php/** * Created by PhpStorm. * User: Administrator * Date: 2017/11/10 * Time: 15:29 */class RsaLogic { ???private $public_key = ‘‘; //公密钥 ???private $private_key = ‘‘; //私密钥 ???private $public_key_resource = ‘‘; //公密钥资源 ???private $private_key_resource = ‘‘; //私密钥资源 ???/** ????* 架构函数 ????* @param [string] $public_key_file ?[公密钥文件地址] ????* @param [string] $private_key_file [私密钥文件地址] ????*/ ???public function __construct($public_key_file,$private_key_file) { ???????try { ???????????if(!file_exists($public_key_file) || !file_exists($private_key_file)) { ???????????????throw new Exception(‘key file no exists‘); ???????????} ???????????if (false == ($this->public_key = file_get_contents($public_key_file)) || false == ($this->private_key = file_get_contents($private_key_file))) { ???????????????throw new Exception(‘read key file fail‘); ???????????} ???????????if(false == ($this->public_key_resource = $this->is_bad_public_key($this->public_key)) || false == ($this->private_key_resource = $this->is_bad_private_key($this->private_key))) { ???????????????throw new Exception(‘public key or private key no usable‘); ???????????} ???????} catch (Exception $e) { ???????????die($e->getMessage()); ???????} ???} ???private function is_bad_public_key($public_key) { ???????return openssl_pkey_get_public($public_key); ???} ???private function is_bad_private_key($private_key) { ???????return openssl_pkey_get_private($private_key); ???} ???/** ????* 生成一对公私密钥 成功返回 公私密钥数组 失败 返回 false ????*/ ???public function create_key() { ???????$res = openssl_pkey_new(); ???????if($res == false) return false; ???????openssl_pkey_export($res, $private_key); ???????$public_key = openssl_pkey_get_details($res); ???????return array(‘public_key‘=>$public_key["key"],‘private_key‘=>$private_key); ???} ???/** ????* 用私密钥加密 ????*/ ???public function private_encrypt($input) { ???????openssl_private_encrypt($input,$output,$this->private_key_resource); ???????return base64_encode($output); ???} ???/** ????* 解密 私密钥加密后的密文 ????*/ ???public function public_decrypt($input) { ???????openssl_public_decrypt(base64_decode($input),$output,$this->public_key_resource); ???????return $output; ???} ???/** ????* 用公密钥加密 ????*/ ???public function public_encrypt($input) { ???????openssl_public_encrypt($input,$output,$this->public_key_resource); ???????return base64_encode($output); ???} ???/** ????* 解密 公密钥加密后的密文 ????*/ ???public function private_decrypt($input) { ???????openssl_private_decrypt(base64_decode($input),$output,$this->private_key_resource); ???????return $output; ???}}
示例：
$all = $this->getPost(‘all‘); ???????$public_key = dirname(__DIR__).‘/logic/public_key.txt‘; ???????$private_key = dirname(__DIR__).‘/logic/private_key.txt‘; ???????$rsa = new ?RsaLogic($public_key, $private_key); ???????$all = $rsa->private_decrypt($all); ???????echo $all;exit;
