How to create random hex message

[DeaD_EyE]

Similar to bowlofred solution:

import random


def get_random_hex_str(hex_length):
    if hex_length % 2 != 0:
        raise ValueError("hex_length must be even")
    maximum = 2 ** (4 * hex_length) - 1
    value = random.randint(0, maximum)
    return f"{value:0{hex_length}x}"

A cryptographic safe solution is the use of os.urandom

import os
from binascii import hexlify


def get_random_hex_str(hex_length):
    if hex_length % 2 != 0:
        raise ValueError("hex_length must be even")
    return hexlify(os.urandom(hex_length // 2)).decode()
