so, a lot of people are really excited about the upcoming cloud variables in scratch 2.0, and there is a discussion here about making a private chat using hash algorithms.

so i made a simple hash algorithm of my own, and now i'm looking for some beta testers. If you want to participate, go to my project and hash your password, then post it here. i promise i didn't build it so i can find it out, BUT IT SURELY ISN'T SECURE ENOUGH FOR REAL LIFE PASSWORDS, so choose one you don't usually use.

EDIT
fixed online issues, but online is still different than offline, so use flash player and not 1.4 smile
this is because of rounding and floating points, can't really do anything about it :S

Darn, and there was me hoping you'd hashed your actual password... tongue

yeah, of course, so you can brute force it...
NOPE

what did you try to do?
you have to type 'signup', then your username, then your password. You'll then see the hash of your password. copy-paste it here so i can enter you to the beta version on the 17th smile

I believe there will be a block that says which Scratch user is viewing the project, so you wouldn't really need any hash algorithms. Just need to check the usernames to see if they are the only ones allowed to chat.

roijac · 2012-05-15 09:46:20

even better big_smile

I hashed to this: 5614293778228025272034840052097943230189510160467388529900469116222707557447160737151187558933350735584720321843038164227771292329353805522300797217437214841073426091473739965514661763860241672571731554235173914434087401666126798688718984161082959151137042116790475556675220871097080484833750909814743586098803

Hmm, that appears to be what I got and also what the default is.

Wow it's almost like everyone's is the same

roijac · 2012-05-15 10:24:25

yeah, i know it's broken hmm

EDIT: seems like i did broadcast instead of broadcast and wait roll
so yeah, it came always the same pretty much.
I also updated the hash algorithm a bit, so try to crack it big_smile
(and post your hashed passwords, of course tongue )

use the flash player?

Use the join block maybe?

roijac · 2012-05-15 11:15:47

nope, it's because numbers are too big and are being converted into sci notation
i fixed it, but the algorithm still yields different results online/offline
so make sure to use the flash player, that's what my project will use smile

I know why it converts it to scientific notation. However, since the join block converts numbers to strings, you could have used that too to display the hash smile

I think it is using join... tongue

I'm going to use this for my social game (Similar to Webkinz/Club Penguin). Nice job on the scripts! BTW, what does 'salted' mean in the program?
