ThinkPHP Rsa加密类怎么用
百度出来说要加载openssl模块,phpinfo();显示下图
代码如下:
$e=Rsa::encrypt('hello',$publickey);
echo $e;
echo Rsa::decrypt($e,$privatekey);
运行时无报错,也没有任何输出;
源码中方法如下,
public static function decrypt($message, $private_key, $modulus, $keylength)
这里的modulus,keylength是什么意思

我目前使用的类

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,
