WebContribute to AnoTherK-ATK/cryptohack-writeups development by creating an account on GitHub. WebIn modular arithmetic this operation is equivalent to a square root of a number (and where x is the modular square root of a modulo p ). For example, if we have a = 969 and p = 1223, we get: x 2 = 968 ( mod 1223) For this we get a solution of: 453 2 = 968 ( mod 1223) If we have a = 1203 and p = 1223, we get: x 2 = 1203 ( mod 1223) design of tattoos of names
