WebMar 2, 2024 · Generate Random Integer in Python. The random library makes it equally easy to generate random integer values in Python. For this, you can use the randint () function, which accepts two parameters: a= is the low end of the range, which can be selected. b= is the high end of the range, which can also be selected. WebIn this case we will use Python to generate a random n-bit prime number. In RSA, for example, we take two prime numbers (p and q) and then multiply them together to create a modulus (\(N\)). The value of N is then part of the public and the private key. For RSA-2048 we use two 1,024-bit prime numbers, and RSA-4096 uses two 2,048-bit prime numbers.
