if n % p == 0: return n == p
d = n - 1
s = 0
while d % 2 == 0:
d //= 2
s += 1
for _ in range(k):
a = randint(2, n - 2)
x = pow(a, d, n)
if x == 1 or x == n - 1: continue
for __ in range(s - 1):
x = pow(x, 2, n)
if x == n - 1: break
else: return False
return True p = q = 0
while not is_prime(p) or not is_prime(q) or p == q:
p, q = randint(100, 1000), randint(100, 1000)
n = p q
phi = (p - 1) (q - 1)
e = 65537 # Common public exponent
d = pow(e, -1, phi)
print(f"Public Key (e, n): ({e}, {n})")
print(f"Private Key (d, n): ({d}, {n})") Applications:
