I present you a crackme based on the "activation of the program" PS: My antivirus is swearing, but it's a false positive and honestly I can't figure out why, if anyone knows the reason, please share it in the comments or discord (nickname is the same)

It consists of four groups of 4 bytes each, separated by three '-' bytes (0x2D). Each of the 16 checked bytes must be a multiple of its corresponding divisor. The divisors per group are: Group 1 (bytes 0-3): 2, 3, 5, 8 Group 2 (bytes 5-8): 5, 7, 12, 19 Group 3 (bytes 10-13): 11, 15, 26, 41 Group 4 (bytes 15-18): 23, 31, 54, 85 Bytes 4, 9, 14 must be exactly 0x2D ('-').
