windows环境的话 可以使用支付宝的secret_key_tools_RSA_win.zip

JSEncrypt下载

使用的话 就比较简单了

js里加载上bin目录下jsencrypt.min.js

// Encrypt with the public key...
          var encrypt = new JSEncrypt();
          encrypt.setPublicKey(pubkey); // pubkey是公钥内容
          var encrypted = encrypt.encrypt($data);

PHP端

// 解密
        function decrypt($data){
            if (!$data) {
                return false;
            }
            if(!openssl_private_decrypt(base64_decode($data), $decrypt_data, RSA_PRIVATE_KEY)) {
                return false;
            }
            return $decrypt_data;
        }
