Static Methods

jacobi(BigInt a, BigInt n) → int

Calculates the Jacobi symbol (a/n) for given integers 'a' and 'n'.

modularSquareRootPrime(BigInt a, BigInt p) → BigInt

Calculate the modular square root of 'a' modulo prime 'p' using algorithms from the Handbook of Applied Cryptography (3.34 to 3.39).

polynomialExponentiationMod(List<BigInt> base, BigInt exponent, List<BigInt> polymod, BigInt p) → List<BigInt>

Computes the modular exponentiation of a polynomial represented by base to the power of exponent, using the specified polymod and modulus p.

polynomialMultiplyMod(List<BigInt> m1, List<BigInt> m2, List<BigInt> polymod, BigInt p) → List<BigInt>

Multiply two polynomials represented by lists 'm1' and 'm2', reducing modulo 'polymod' and prime 'p'.

polynomialReduceMod(List<BigInt> poly, List<BigInt> polymod, BigInt p) → List<BigInt>

Reduce a polynomial 'poly' modulo 'polymod' using prime 'p'.
