本文实例讲述了php基于openssl的rsa加密解密。分享给大家供大家参考，具体如下：

<?php $config = array( //"config" =>"D:/phpserver/Lighttpd/openssl.cnf", //'config' =>'D:/phpStudy/Lighttpd/OpenSSL.cnf', 'private_key_bits' => 1024, // Size of Key. 'private_key_type' => OPENSSL_KEYTYPE_RSA ); //$res = openssl_pkey_new(); $res = openssl_pkey_new($config); // Get private key // openssl_pkey_export($res, $privkey, "PassPhrase number 1" ); openssl_pkey_export($res, $privkey); var_dump($privkey); // Get public key $pubkey=openssl_pkey_get_details($res); // echo "------------> "; // print_r($pubkey["rsa"]); // $bin_str=$pubkey["rsa"]["n"]; // print_r($bin_str); // echo " "; // //echo $bin_hex_str = pack("H*" , bin2hex($bin_str)); // echo $bin_hex_str = bin2hex($bin_str); // echo " ------------< "; $pubkey=$pubkey["key"]; // var_dump($privkey); // var_dump($pubkey); echo $privkey." "; echo $pubkey." "; ?>
