I've got another request, add a button to the computers that allows you to take a screenshot of the screen and then saves that into a folder.

I second that!

Me too!

The screenshot should be correctly sized, saved to a file and to the clipboard.

I think it should just take a snapshot of the computer screen itself (border excluded) and save it to the desktop, preserving any possibly important data in the clipboard.

3/10 reasonable but the angle is off, the shadows are barely visible and the reflection is horrible

0/10 its even easier do in c4d . LOL

just mograph text , a few light source , floor / large plane, make floor white and reflective , turn on ambient occlusion also global illumination easy

i will make own copy of it now

you have no idea.

first of my problems was the surface turning black after i turned on reflections, i had to use a shader mat i dunno what it was called.

#247547 SHA-256 in Pure Lua

I'd be interested if you could implement bcrypt in Lua.

I've been actually looking into implementing Blowfish and bcrypt in CC a few days ago, but note that that algorithm is designed to be slow and having it in CC will make it even slower.

Wouldn't that be perfect for password systems? It would take quite a bit longer to brute-force it.

You have to assume that if someone wants to crack a password that was found in a CC program, he will certainly not crack it from within CC.
Cracking outside of CC will always be faster, so might as well make them as fast as possible for convenient in-game use.
BCrypt has an argument that determine the cost factor, it won't be much before a cost factor get's too costly for CC to be any more useful against offline cracking, compared to SHA2 alone.

Well, outside of CC it would still be slower than SHA256.

#249070 SHA-256 in Pure Lua

Posted by LoganDark on 29 March 2016 - 02:03 PM in APIs and Utilities

Anavrins, on 19 February 2016 - 09:41 PM, said:

I ended up making my own take at implementing SHA256 in Lua and ended up being around 15x faster.
With some rough speed test I could only get up to 105 hash/sec, my implementation was able to get to 1500 hash/sec.
It's still not much compared to say, gpus, but it's quite something for CC.
I also noticed the same thing as Shazz, that any input that's (64*n)+55 bytes in length will produce the incorrect hash, I didn't go deep into the problem, but I know it's the pre-processing part that produces an incorrect padding.
That bug is not present in my implementation.
Here's the pastebin: 6UV4qfNF

It seems I'm having a little bit of an error trying to run your SHA algorithm after having an upcoming project of mine mostly finished.

Edit: just using sha256("msg")

It's so awesome that you made this, do you mind if i put this in my new program? I've given you a bit of credit and put a link to this thread, is there anything else that you want me to do or is it fine the way I've done it? Thanks.

I'm sure he won't mind. I've used it in the first, second and third versions of my password lock with no problem. ( ͡° ͜ʖ ͡°)

Yeah, I bet Mimic is using a different version.
Edit: bit doesn't have a bad lshift

Ah yes, as much as I appreciate the work of it's dev, I find that mimic has a lot of issues.
There's nothing wrong with lshift, but definitely with rshift, with number approaching 2^32, I could only get correct results with my own implementation of it.
I ended up modifying the code so that it automatically uses bit if bit32 is not found, it's on the same pastebin link.

Well, that won't be a problem unless someone creates an extremely long password.

What CC version are you using, this implies that your using an older version of CC which does not contain bit32.
In any case you can replace the bit32 parts with bit, though I haven't tested it.

Yeah, I bet Mimic is using a different version.

Edit: bit doesn't have a bad lshift
edit 2: I'll copy the functions from the bit32 API and put them in your hashing function. It should fix issues with older versions.
edit 3: not needed, bit does have a blshift but not an lshift.

edit 4: too long without yielding

Edit 5: I'm using the original API because it works on older versions. It may not be as fast, but that's the compromise you have to make when nobody considers the older versions...

#253746 AES Encryption

Posted by LoganDark on 14 June 2016 - 07:18 AM in APIs and Utilities

If you haven't noticed this is not a one-way hash. If you're using it for storing passwords or something that should not be decrypted this is not the system for you. Something that is encrypted can be decrypted by brute force. I recommend a one-way hash function such as SHA256 or PBDKF2 (I got the name right !).
