[Plugin] Whirlpool

Whirlpool

Introduction

Very simple plugin. Just provides an implementation of the whirlpool hash algorithm for PAWN. This is so that you don't need to use bad hash systems like MD5, plain awful ones like Adler32 (UDB_Hash) or ones that aren't even true hashes (encode).

Unlike most other hash functions (MD5 and SHA1 included) there are no known weaknesses in whirlpool, so you can be sure your hashes are secure.

Use

This plugin adds just one function:

native WP_Hash(buffer[], len, const str[]);

So I didn't bother including an include. To use simply call the function, passing a buffer of at least 129 characters, the size of that buffer and the string you want to hash. This used to say 145 but I have no idea why! You need 128 for the hash and 1 for the NULL terminator

Example

#include <a_samp>

native WP_Hash(buffer[], len, const str[]);

main()
{
    new
        buf[129];
    printf("hash");
    WP_Hash(buf, sizeof (buf), "The quick brown fox jumps over the lazy dog");
    print(buf);
}

That will output:

B97DE512E91E3828B40D2B0FDCE9CEB3C4A71F9BEA8D88E75C4FA854DF36725FD2B52EB6544EDCACD6F8BEDDFEA403CB55AE31F03AD62A5EF54E42EE82C3FB35

Which is the correct hash for that string.

Notes

If you use YSI that uses a custom key-based hash algorithm, while there are currently no known cracks for it I do not know exactly how secure it is, however the key system vastly improves it's security from server to server. You may want to consider upgrading to Whirlpool however YSI is the only user system which actually bothered with anything resembling security, so it's not required.

As with all my plugins if you place the folder in your SA:MP directory then compiling the plugin will automatically place the new dll or so in your plugins directory.

Version

I have no intention of modifying this in any way as it works fine. So as far as I'm concerned this is 1.0.

I compiled the project in Ubuntu 8.10 (32bit): http://www.kowaz.hu/downloads/Whirlpool.so
And remove the $(GPP) $(COMPILE_FLAGS) ./Source/*.cpp line from the Makefile, because there isn't a "Source" folder in the package.

Very nice work, I've never heard before about this hashing algorytm.

Awesome, I've seen on Seif Admin script that there's an include? :O

Seifs admin script uses MD5 hashed passwords, and the MD5 include is made by Y_Less too i think

great job Y_Less

Nice work. In December 2007 I wrote something similar you may be interested in, SAMPCrypt. It provides cryptographic natives that will hash both strings and files located in \scriptfiles in the following implementations: MD5, SHA-1, SHA-224, SHA-256, SHA-384, SHA-512, WHIRLPOOL, and RIPEMD160. All of the algorithm implementations are public domain C code. Intended on adding more but I got bored with it - if you would like I'll upload the code.

Y_Less, your link to Wikipedia isn't correct. You're missing a ")" at the end. Then it should be fine.

Good work again Y_Less.

Great plugin, this will be useful!

Thanks Popz for saving some precious time.

Added cheers. I'll update the makefile later, it was based on the YSI one, I thought I got everything, apparently not.

I knew you had written one like this, but I thought it wasn't released. I'm not too bothered about the code as as you said they're in the public domain and I've written MD5 in PAWN before, but I'm sure others would benefit from it. So it's entirely up to you. Actually come to think of it I wouldn't mind seeing how you implemented them, even if just for interest.

Nice work.
