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;">
"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 $pubkey."
"; ?>
"; // print_r($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."
"; ?>
