    u(t) is called 60 times per second.
    t: Elapsed time in seconds.
    S: Shorthand for Math.sin.
    C: Shorthand for Math.cos.
    T: Shorthand for Math.tan.
    R: Function that generates rgba-strings, usage ex.: R(255, 255, 255, 0.5)
    c: A 1920x1080 canvas.
    x: A 2D context for that canvas.

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
