how the common decryptor cracks the software. This requires knowledge and practice other than general software development, ordinary people do not have the time and energy. Even if you know some decryption knowledge and even try a little bit, the level of encryption and decryption in this industry is particularly different. A person may think that he has come up with a particularly good idea to encrypt the data. However, in the eyes of the experts, i

registered, do not let it call the same function or determine the same global flag. 3. Insert a large amount of useless computing code when checking registration information. This is intended to mislead the decryptor and make them think they have found a real method of cracking, but they find it ineffective after trying it. It's like soldiers on the battlefield disguise themselves with "camouflage servers" and straw. It's hard for the enemy to find o
