My task is for educational purposes, and I have been offered the challenge from a friend, however, I'm stuck on this question:
This task may be fun for some folks. But basically, I think it's AES.
The input: G9S4DZ2 or 35419946942 (which is just base10 of first variable)
which is base64 for: 900HKyJ+TSqvbyaNNpHJXA==
From there, I have no idea what the encryption type is :(
