Elliptic Curve Calculator

for elliptic curve E(Fp): Y^2 =X^3+AX+B , p prime

         
  mod p
(be sure its a prime, just fermat prime test here, so avoid carmichael numbers)

 

A
B  
(will be calculated so that point P is on curve)
  point P
x :

 
 
y: 



point Q
x:     
it's your own responsibility to ensure that Q is on curve
y:
  number  n  
   
 
  Result:
  
x:
 
y:
   
  Order of point P:
-will only give you result for fair sizes of p (less than 1000)
calculate k for kP= O

Update: 22.04.2016: bug detected - discriminant calculations does not work for B=0. sorry. to be fixed.
