Completed algorithms in Sys360 (cuz I’m tried, I just finished writing the quick 3 line alder algo and the not so quick tea family algorithms):

~RC4
~MD4
~MD5
~SHA1
~SHA224
~SHA256
~SHA384
~SHA512
~ADLER32
~CRC32
~TEA
~XTEA
~BTEA (also known as XXTEA)
~Kerberos encryption/decryption

More to come

So I was getting bored of programming Xbox stuff into Sys360 so I continued on the Security API portion and wrote a class for TEA, XTEA, and XXTEA… it’s just odd because I have to make work around’s for endian-ness of the algorithm… mainly due to the fact that it works with 2 integer blocks (32 bit TEA algo with 2 uints, 64 bit TEA with 2 ulongs), but the C standard source code takes the blocks as a parameter which means the user has to specify the endian of how the blocks are loaded… weird stuff >.<

There’s been some questions about this project, I’m taking a break from coding it to answer them.

s3 = abbreviation for Sys360

Q: What’s the difference between Sys360 and X360?

A: A paw-full of things, first off, it’s in a different language which expands my horizon on it. I am basically creating my own environment. To be honest, X360 is coded sloppy-like and it’s not fool proof. In s3, I am taking time to make sure my code is fast, efficient, and more reliable to not fail. Besides that, I am including classes and sources that are extra, besides the ones in X360. Also, it is to contain a full (CUSTOM built) Security library, big integer class, etc etc, which is cool for others, but mainly essential to the library.

In short: More, Better, and Faster.

Q: This is in native C++, will there be wrappers for it?

A: Of course there will be, I mainly did C++ for portability between OS, speed, and interface, but I know .NET whores would love it. Due note, I won’t make the wrappers until after the library is complete.

Q: Is it going to be open source?

A: I am not sure at the moment, not due to the usual kiddie “he’s done gon’ steal mah source which makes mah manhood feel small!” No, it is not that, in fact, it is because of kiddies like that that I MIGHT be changing things up here. And when I say that, I mean… Sys360 will have a spot on my site for documentation, everything detailed out on how to use, examples, and even fractions of source code. But, kids for some reason think “stream.Write(a few values here and there)” makes there program all god like and they don’t realize that anyone can know how the program mods the save by comparing a non modified file to one that was put through the program. So, they decide to not abide by the rules. Well, Sys360 will be… closed source, open documentation and fractions of source code. License will still apply, users will have to release open source. BUT, I am also thinking about paid user licenses, anywhere from 60 – 100 bucks PER APPLICATION for me to waive the open source policy on that program. Free user = open source, customer = not.

Again, this is all in decision mode right now.

Oh and, all closed source stuff would just be Xbox specific, anything else such as, Crypto API, biginteger class, IO class, etc etc is all going to be open sourced

Q: What does this mean for Le Fluffie and X360?

A: X360 I’m abandoning that trash :p Le Fluffie will be updated to work with s3, mainly for easy plug-in capabilities and… Windows GUI API is annoying as fuck…

Q: Can you teach me how to <do an xbox related topic>?

A: Sorry, no, I am not a teacher, I am not your slave, I juggle friends, raves, DJing, programming, school, and trying to find internships.  No time for your stupidity.

Any other questions? Feel free to ask

So I’m pretty much done with STFS package parsing and allocating of blocks (of course hashing as well) and STFS streaming. I’ve finished my Account class, which is a lot more easier (as well as more editable). Now, I’m currently working on FATX. So I’d say with in a month or two (if I can keep up such progress hopefully), people shall have Sys360, better, faster, and more efficient library.

After some hours of debugging, I have a positive feeling that I have completed STFS streams, though, as with any programming, you can never be too sure   But, I have tested it, wrote past the end of a stream and tested the allocation of new blocks, so now, anyone can read and write to the files directly in the STFS package without having to extract and inject them :3
RAWR CLEEKZ MEH

So ya, as you know I’ve been working on my Sys360 again, tbh, before I was just lazy and didn’t feel like coding cuz… as hard as it may seem, it’s not really difficult just… time consuming… and I’m a lazy fuck. But now that I’ve actually decided to work on my library and force myself to code, I’m actually progressing really fast. Main STFS structure and reading is done. I’m currently working on fast STFS streaming for file (so say you wanted to open up a GPD without extracting it, the package could read it inside the package and will be able to write to it). And that’s going to be the main use of STFS rather than extracting and injecting (for me at least, the process is faster than extracting/injecting).

Here’s a random code segment o_o

Not done, but I’ve been doing lots and lots and lots of work on it lately o_o
RAWR! (click me full size :3)

I’ve been working a lot on Sys360 lately, mainly redoing my Stream system and working on my big Integer class. With my streams, I made it a little bit easier because I started using templates a lot more, therefore, I can create special classes in special cases without having to copy and paste exact similar attributes. With my big int class, I think I’m finished on it o.o

Also… I JUST BOUGHT the $700 Rane SL3 kit for Serato (DJ software) XD Being delivered to my house today… gotta go to work tho… >_<
