File encryption method and device, electronic equipment and storage medium

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...

Problems solved by technology

[0002] With the development of network technology, information security has become the focus of attention. If files are transmitted on the network in plain text or stored in plain text, it is very likely to cause file leaks

In order to prevent file leakage, the encrypted file is usually encrypted. After the existing encryption method encrypts the file, the data volume of the encrypted file usually becomes large, resulting in a waste of transmission resources and storage resources.
