Abstract

The invention discloses a generation method of an encrypted file. The method is executed in the computing equipment, and comprises the following steps: acquiring a password for encrypting an outgoing file to be transmitted to target equipment and processing authority for processing the outgoing file on the target equipment by a target user; encrypting the outgoing file by using the password to generate a cipher text content; extracting various processing logics required for decrypting and controlling the cipher text content on the target equipment and packaging into a data set packet; adding the processing authority and the cipher text content into the data set packet to establish an executable file. The invention also discloses a generation device of the encrypted file and the computing equipment comprising the device.

Description

technical field [0001] The invention relates to the fields of computers and the Internet, in particular to a method, device and computing equipment for generating encrypted files. Background technique [0002] With the popularization and development of computer technology and network technology, more and more users transfer files via the network. These files are usually transferred between users in an uncontrolled manner. For example, when a file is sent from one user to another via the network, the original user has no way to control how the new user uses the file. For example, the new user can print the file, copy the content of the file, Send files to other people, etc. [0003] In some cases, especially in some business environments, the file owner wishes to be able to control how the file recipient uses the file after sending the file to the other party. For example, the number of times the file recipient can browse the file, the permissions of the file recipient to ...
