md5_string_unicode(string)
| Argument | Description |
|---|---|
| string | The string to hash. |
Returns: String
In cryptography, MD5 (Message-Digest algorithm 5) is a widely
used cryptographic hash function with a 128-bit hash value and has
been employed in a wide variety of security applications. It is
also commonly used to check the integrity of files and strings.
This function will take an input unicode string (which is 16bits
for each char) and return the 32-character hexadecimal MD5 hash
that is unique to that string. In this way you can generate a
secure key which can be stored and used to check the integrity of
the information being sent to (or received from) an external server
(for example).
NOTE: There are two formats for the MD5 encoding, UTF-8
and unicode. Both are provided to facilitate communication with
different server setups, but the most common to use is
unicode.
var hash, str;
str = base64_encode(game_data);
hash = md5_string_unicode(str);
http_get("http://www.MacSweeneyGames.com/CatchTheHaggis/gamedata?hash="
+ hash);
http_get("http://www.MacSweeneyGames.com/CatchTheHaggis/gamedata?data="
+ str);
The above code will base64 encode a string and then generate an MD5 hash. Finally, both the hash and the encoded string are sent to a server.
