lockdown source

[Rob]

Based from the code that iago released.

This should work on any x86 system.  Tested on windows/linux/freebsd.

Want to tell us what this does? I thought iago's was fully functional..

[iago]

Mine was fully functional, but not especially clean. I got lazy on the last few functions and did a straight asm -> C conversion, with little of the original logic clean/intact.

Rob, do you mind if I mirror that? I'd like to put a link to it in my Wiki, and I don't like linking other people's sites (since stuff sometimes moves around and breaks links).

Maybe Hdx will release his Java version, that'd be sweet :)

I don't mind.  Go ahead and mirror it.

It's a bit ugly in the PE section, as it got tedious after a while. I'll clean it up eventually but meh. To bad java doesn't have structs :*(

[iago]

Keep in mind that a struct is a class with all public variables :P

[rabbit]

And a complete lack of methods :P

[iago]

In C++, I think you can put methods in structs. Of course, C++ isn't a good example of a language. :P

I suppose you could do function pointers, which is basically a method. :)

[rabbit]

C++ fails though.  Why would anyone use it?  Structs are structs, classes are classes.  Let's leave it at that, k?

[iago]

There's nothing wrong with C++, it's the language where structs and classes came from, so I think it's a good one to talk about if you want to discuss those.

It would be great to simply it to what you said, but like Hdx said, Java doesn't have structs. However, like I said (and you improved), a struct is just a class with only public member variable and no functions. As a result, you can simulate structs in Java fairly easily.

Simulate something? in java? How absurd!

[Hdx]

Thats what I did. But it makes copis of each value, increasing the memory usage.

[Joe]

Using too much memory? In java? How absurd!

Java doesn't use a lot of memory unless you're using a graphical interface, such as Swing. But console Java doesn't use much more memory than equivalent languages.

[Hdx]

The very basic java app that I wrote that does ntohing but have a single thread and do some math used a whole 8k memory.
It's the fact that I'm loading ~1mb per lockdown, (I should really look and see if I can make that more efficient by useing 1 file.)
And ~20mb in other hashes..
It's pretty gay.
I'll optimize it eventually.
