Cryptography calculator

In this page we have a calculator that is more powerful than ordinary calulators for performing modular arithmetic operation with large integers.

Modular arithmetic

a =
b =
m =

answer =

Extended Euclidean algorithm

a =
b =

answer =
Finding units and inverses
We want to find at most units mod starting after .

Finding the smallest factor ≥ 2

We want to find the smallest factor (≥ 2) of

answer =
Jacobi symbol
a = b =
The computation will be shown here.
