Will throw 7 if the decryption works correctly. #slow
u/katkip

it lags so much
u/f8f82804

it should be possible to optimize the modular inversion and exponentiation, but it would probably go over the character limit

Hot damn! that looks fancy! and i thought i was doing something great by just adding random colour :D
u/Xen

always save your code to one side before posting, play with it to see if you can squeeze something extra out.
u/karan

Helpful tips! Is there an IRC or some messaging service to hang out with fellow dwitters?

I couldn't fit in scaling by "s", either via x.font or via x.setTransform or x.scale. This is also broken on iOS Safari because x.filter needs the trailing semicolon on that browser.
