Abstract

The invention provides a file encryption method and device and a file decryption method and device. The encryption method comprises the following steps of obtaining a binary byte stream correspondingto a to-be-encrypted file from a local first folder appointed by a user; performing operation on the obtained binary byte stream corresponding to the to-be-encrypted file and the binary byte stream corresponding to the encryption password set by the user to obtain a binary encryption byte stream corresponding to the encrypted file; and storing the encrypted file in a local second folder specifiedby the user, and deleting the to-be-encrypted file from the first folder. Therefore, the file can be encrypted efficiently and conveniently.

Description

technical field [0001] The present disclosure relates to the technical field of file encryption, and in particular, to a file encryption method, a decryption method, and a device. Background technique [0002] In the prior art, when the user encrypts the photos and images stored locally on the mobile phone, the method generally adopted is to upload the photos to the cloud for encryption, such as uploading to Baidu Cloud, etc. The album is encrypted by setting a password to open it; although the first method has certain security, it requires users to upload photos to the cloud, which is relatively inefficient; in the second method of setting a password to open the album, if the Some photos that do not need to be encrypted are stored in the photo album. If the user needs to open such photos for viewing, he still needs to enter the password to open the photo album to view, so there is also some inconvenience. Contents of the invention [0003] The present disclosure provides...
