http://www.numbertheory.org/php/tonelli.html WebbLuckily, if the prime is of format 4k + 3, one can find the square root with just 1 modular exponentiation instead of 5 - 10 for Tonelli Shanks solving the general case. So the problem was changed to only support these primes, the TL and success probability was suddenly more than enough.
