AI Technical Summary

Problems solved by technology

This file encryption method makes it more complicated to obtain the encrypted packaged file in the packaged file, and increases the difficulty of obtaining the file content in the packaged file
Moreover, this method slices and cuts the file according to the file feature information. Just by disrupting the file block sequence, the file feature cannot be completely eliminated, so it is easy for a malicious third party to easily recover some or even all of the valuable information.

Abstract

The invention provides a file encryption method. The file encryption method comprises the following steps: splitting a target file into a plurality of fragmented files; based on each fragmented file,generating a check code by using an information digest algorithm, and encrypting each fragmented file by using the check code; packaging the plurality of encrypted fragmented files into a compressed file package; generating a path of the compressed file package; and encrypting the path by using an AES encryption algorithm. The invention further provides a file decryption method. The invention further provides a distributed storage system, electronic equipment and a readable storage medium.

Description

technical field [0001] The present disclosure belongs to the technical field of file storage management, and in particular, the present disclosure relates to a file encryption and decryption method, a distributed storage system, a device and a storage medium. Background technique [0002] With the further development of networking, in real life, there are a large number of documents belonging to the secret-level documents of enterprises and institutions, such as contracts, technical solutions, personnel information and so on. [0003] With more and more network informatization, all kinds of hackers flood the network, data security storage has become a key concern of modern social enterprises and institutions, and the development of enterprise informatization has brought new challenges to the security management of files. [0004] On the other hand, with the continuous evolution of encryption algorithms and becoming more and more mature, it brings more options for encrypted s...
