Method for security encryption and signing based on identity file

Abstract

The invention discloses a method for security encryption and signing based on an identity file. The method includes: obtaining configuration information of basic setting of a client and configuration information of advanced encryption standard setting of the client; registering and applying the identity file applicable to a mailbox at a server end; downloading data information of the identity file through the client; obtaining type information of a task to be executed selected by the client; and performing encryption and decryption to files through the client according to the identity file. By the method, important data of a user can be protected from being viewed or modified, safe communication on an originally unsafe channel can be achieved, and denial behaviors after using the user's identity to receive and transmit information can be avoided.

Description

technical field [0001] The invention relates to a software system, in particular to a security encryption and signature method based on an identity file. Background technique [0002] This year, with the rapid development of the Internet, people began to understand and learn Internet knowledge more and more deeply. While the Internet provides people with convenience, there are many security risks. The files and information people send It is often leaked and stolen, which brings great inconvenience to people's life, study and work. [0003] Although there are many ways to encrypt and decrypt files at present, the safety factor of these methods is not high, and there is still the possibility of being modified and stolen when transferring files on an insecure channel, so people need a price that meets the requirements more Encryption and decryption system. Contents of the invention [0004] The invention mainly aims at the deficiencies of the prior art, and provides a secur...
