Embodiment Construction
[0021] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.
[0022] see figure 1 As shown, the cracking protection method of SWF file in the embodiment of the present invention comprises the following steps:
[0023] S1: Call the C language to write the core SWF file through Action Script in the disk, so that the core logic of the SWF file is not easy to be reversed and decompiled. The file data of the core SWF file is encrypted by an encryption algorithm (the file data that needs to be encrypted is read from the disk to the computer memory, and the file data is encrypted and then rewritten to the disk); the encryption algorithm is AES (Advanced Encryption) in this embodiment. Standard, Advanced Encryption Standard) encryption algorithm, and other encryption algorithms can also be used in practical applications.
[0024] In order to increase the cracking difficulty of the core SWF file, an encryption ...
