Embodiment Construction

[0024] In order to better understand the present application scheme, the technical solutions in the present application embodiment will be described in connection with the drawings in the present invention, and the technical solutions in the present application will be clear and completely described.

[0025] With the development of network technology, information security has become the focus of attention, and if the file is transmitted in the form of a plaintext, or stored in a clear text, it is very likely to lead the file. In order to prevent file disclosure, the encrypted file is typically encrypted. After the existing encryption method is encrypted with the full text of the file, the amount of data that is encrypted after the encrypted file is usually large, causing waste of resources and storage resources.

[0026] In response to the above technical problems, the inventors have found and propose a file encryption method, device, electronic device, and storage medium to dete...

Abstract

The invention discloses a file encryption method and device, electronic equipment and a storage medium, and relates to the technical field of encryption. A to-be-encrypted file is obtained, the to-be-encrypted file comprises a plurality of data frames, each of the plurality of data frames comprises a frame header and a frame body; then a to-be-encrypted data frame is determined from the plurality of data frames; the frame header included in the to-be-encrypted data frame is obtained as the to-be-encrypted frame header, and the to-be-encrypted frame header is encrypted to obtain an encrypted file. The to-be-encrypted frame header is encrypted, and the frame body is not encrypted, so that the data volume of the encrypted file is small, and network transmission resources and storage resources can be saved.

Description

Technical field [0001] The present application relates to the field of encryption technology, and more particularly to a file encryption method, device, electronic device, and storage medium. Background technique [0002] With the development of network technology, information security has become the focus of attention, and if the file is transmitted in the form of a plaintext, or stored in a clear text, it is very likely to lead the file. In order to prevent file disclosure, typically treat encrypted files, existing encryption methods are encrypted with files, usually make the data volume of encrypted files great, resulting in transport resources and storage resources. Inventive content [0003] In view of the above problems, this application proposes a file encryption method, device, electronic device, and storage medium to solve the above problems. [0004] In the first aspect, the present application provides a file encryption method to obtain a file to be encrypted, wherein...
