Abstract

The invention discloses an electronic file processing method and device, a storage medium and a processor. The method comprises the following steps: acquiring a signature certificate and file content in a target electronic file; determining a first key of the signature certificate and a first hash value corresponding to the first key; obtaining a second key and to-be-verified data preset at a target node position of the target electronic file, and a second hash value corresponding to the second key; respectively comparing whether the first secret key and the second secret key are consistent with the to-be-verified data and whether the first hash value and the second hash value are consistent to obtain a comparison result; and if the comparison result is consistent, normally running the target electronic file, otherwise, stopping running the target electronic file. The technical problem that in the prior art, the code signature verification process on a Windows platform is achieved in a user mode program, and the integrity and safety of software cannot be protected under the condition that efficiency is not affected is solved.

Description

technical field [0001] The present invention relates to the field of file processing, in particular to an electronic file processing method and device, a storage medium and a processor. Background technique [0002] At present, as the 64-bit Windows operating system is widely used in people's daily office and entertainment environments, application software has also been adapted accordingly with the upgrade of the operating system, and the development of genuine application software has become more and more regular. In order to ensure the integrity, security and compatibility of the released software itself, software developers generally purchase digital signature certificates through formal channels to sign and release software. On the one hand, it can ensure the integrity and security of its own software, and on the other hand, it can be better compatible with the scanning mechanism of anti-software security software, thus bringing users the guarantee of safe and stable op...
