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 />";?>
