Embodiment Construction
[0017] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments. Assume that the source data file is stored in the C drive, and the data file name is A, such as figure 2 Its workflow is shown as follows:
[0018] Create an empty data file in the same directory, named A1, which is used to store the encrypted data file; read the data file from the source file A, use the AES encryption algorithm to encrypt the data in A, and write Into A1, before writing to A1, it is necessary to make two judgments on the encrypted file header: the encrypted file header is a part of file A1: (start to perform the judgment operation) when the encrypted file header of A1 is empty, write to it Enter the encrypted file header; when the encrypted file header of A1 is not empty, use the MD5() algorithm to make a second logical judgment on...
