Find a value for D (RSA algorithm)

find_d.py

# This program finds a value for D in the RSA algorithm
# Given values for A and E

A = int(input("A: "))
E = int(input("E: "))

# Start at E so D will be bigger
n = E
while True:
    n += 1
    D = (n * A + 1) / E
    if D.is_integer() and D != E:
        break
D = int(D)
print(f"Found D: {D}")
