Shanks tonelli algorithm
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. Webb22 okt. 2024 · Or, you can write the code for the Shanks-Tonelli algorithm. modroot(vpi(13437),100003) ans = 643. mod(643^2,100003) ans = 13437.
