What is it?

It's yet another hashing functions module for Garry's Mod. I wrote it because I needed MD5 on a Linux server yet couldn't find any other modules who did that. Someone might find the result useful, I suppose.

Usage

require("yahm")
yahm.MD5("somestring")
yahm.SHA1("somestring")

Download

Linux binary (it's huge because I didn't know how to strip the CryptoPP symbols)
Windows binary

Before you get all these people complaining about the .dll being a virus, I'd put it in a zip or rar file.

and I think theres many other modules that do this, but a more simple one like this is great. Thanks!

If there really are people that stupid, then it's their problem. I don't care.

Yes, there are, hence the name of the module.

Now where can I find a unhash module..

From what I know, you can't unhash MD5 or SHA1

It was supposed to be a joke.

Riiiiiight

There are websites where you can unhash both of them

Looking it up in rainbow tables aint unhashing. a smart man would add double encryption (Base64, Rot13 Something like that) to stop the rainbow tables from being usefull.

I have always wondered if an MD5 is 35 numbers/letters long, how is there always a hash for something over 35 characters?

If you make a hash that returns something 2 letters long you have 676 different possibilities, if someone put a string in that was 3 characters then there would be 17,576 different possibilities. If we go to a higher level that "property" or "fact" wouldn't change so one hash can have multiple strings like if you hash a 33 character string?

Google it, you'll find the workings on the encryption algorithm.

You'll find that not every text has to be have a unique hash though, some experts managed to create 3 different PDF files all with the same md5 hash.. (Can also be found on google I think)

yet another time i must post this

md5 is worthless and at least sha-1 takes a fuck lot more work to collide, and this is a pure lua implementation that adds 1 second to start up when loaded to build a cache table but then all sha-1 hashing is damn near instant and you can AddCSLuaFile this to clients so they don't need to have a binary installed.

I posted this in Niggles awhile ago.

Can we have more hash functions?
Like MD5, SHA2, Tiger, etc

+ Added crypto.sha512(string)

Related and useful for all Linux servers.

Please reupload!

[Crap-Head]

Sorry about the bump, but is there any chance that this module could be updated for GMod 13?

Thank you in advance!

Doubt the author will update it, use mine

Could you get around to making that new thread? Just handy to keep up to date instead of diving through other threads trying to find any news about it.

[Wizard of Ass]

Done.
