>>97280I was told not to roll my own crypto, but now I'm seeing arithmetic and I'm beginning to question the first guy's advice.
Who do I pay to make sure my future does not rest in the hands of amoral mathematicians?

>>97295let's say x=1
(1^2+3)^2 = 16
1^4+9 = 10
16 is not 10
sqrt(1^2+9) = sqrt(10)
1+3 = 4
sqrt(10) is not 4
