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) WebFor those who qualified for the finals, you’ll have the chance to solve a few more CryptoHack challenges, but for now, we wanted to go through Bits, explain some potential solutions and some cover a few interesting things we learnt when building the challenge itself.
