WebMar 12, 2024 · In a finite field, there are basically two main algorithms to compute an inverse: The Extended Euclidean Algorithm, also known as as "extended GCD". There is a variant called Binary GCD. In a finite field of characteristic 2, where addition is bitwise XOR, the binary GCD is easier to implement. WebApplications. One of the applications of the Extended Euclidean Algorithm is to calculate the multiplicative inverse of a number. We know that the algorithm gives the GCD of two numbers plus numbers x and y that satisfy the equation ax + by = gcd (a,b). If gcd (a,b)=1, then y is the multiplicative inverse of b mod a. This means that b*y mod a =1. share it updatedWebPyCryptodome is a self-contained Python package of low-level cryptographic primitives. It supports Python 2.7, Python 3.5 and newer, and PyPy.
