PHP: authorization code function development

As required by the project, you must develop an authorization code function. The customer can only use the authorization file. Currently, I have written a class using the built-in php function library mcrypt. However, I think it is too simple. The decryption class is put on the customer's machine and can be easily cracked. Please help me with your ideas.

To increase the maximum difficulty of client cracking, imitate the network activation on Microsoft. Or I have seen desktop software in a client-server architecture, which is equivalent to renting a machine from a developer.

But let me say:In the end, the attack is just a command that bypasses the genuine check, and there is no difficulty. I don't know what your application is. However, for general applications, the customer's willingness to purchase genuine products is increased through rolling upgrade of software, technical support, and other additional values, it is much more effective than various static anti-cracking methods.

Powerful, such as StarForce, is still a new generation (only a matter of time ).

Just encrypt the source code. Zend is recommended. Other tools are slag. After encryption, you can try it out.
