Abstract

The invention discloses a slice file encryption method, a slice file decryption method, a storage medium and electronic equipment. The slice file encryption method comprises the following steps: acquiring password data and file data; performing algorithm operation on the password data to generate character string data; and segmenting the file data according to the character string data to form multiple pieces of file slice data, and sorting and combining the multiple pieces of file slice data according to the character string data to form encrypted file data. The character string data is generated by performing algorithm operation on the password data, and the file data is segmented, sorted and recombined according to the character string data so as to form the encrypted file data, so that only algorithm operation is required to be performed on the password data, encryption algorithm operation is not required to be performed on the whole file data, and the encryption efficiency is improved.

Description

technical field [0001] The invention relates to the field of file encryption, in particular to a slice file encryption method, decryption method, storage medium and electronic equipment. Background technique [0002] The traditional file encryption method is more suitable for the encryption of a small amount of data. For files with a large amount of data, the traditional encryption method performs algorithmic operations on the entire file data, which takes a long time to calculate, and the performance and efficiency of encryption are not satisfactory, which cannot meet the needs of use. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. For this reason, the present invention proposes a sliced ​​file encryption method, which can realize encryption by dividing, sorting and combining file data, which is beneficial to improve encryption efficiency. [0004] The invention also proposes a dec...
