This article mainly introduces the example of using openssl to implement the rsa asymmetric encryption algorithm. Please refer to it

 代码如下: _keyPath = $path;         }           /**         * create the key pair,save the key to $this->_keyPath          */         public function createKey()         {                 $r = openssl_pkey_new();                 openssl_pkey_export($r, $privKey);                 file_put_contents($this->_keyPath .
