php基于openssl的rsa加密解密示例

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 "------------><br />";// print_r($pubkey["rsa"]);// $bin_str=$pubkey["rsa"]["n"];// print_r($bin_str);// echo "<br />";// //echo $bin_hex_str = pack("H*" , bin2hex($bin_str));// echo $bin_hex_str = bin2hex($bin_str);// echo "<br />------------<<br />"; $pubkey=$pubkey["key"];// var_dump($privkey);// var_dump($pubkey);echo $privkey."<br /><br />";echo $pubkey."<br /><br />";?>
