Abstract

The invention provides a method and system for verifying the integrity of files downloaded from a website. The method generates a first verification value according to the stream of uploaded files to form a database A; selects several files to download, and generates a second verification value for each of the files respectively. check value; check whether the second check value exists in the database A, if so, proceed to the next step, if not, prompt download failure; pack the selected files to generate the third check value; Download several files to the virtual memory of the client computer, pack several files in the virtual memory, and generate the fourth verification value; compare the third verification value and the fourth verification value, if they are consistent, dump the combined folder to the client computer, if they are not consistent, it will prompt that the download failed. The invention performs two checks during the file downloading process, which fully guarantees the integrity of the files downloaded from the website, and the whole process does not require human participation, which reduces the possible risk of human operation.

Description

technical field [0001] The invention relates to the technical field, in particular to a system for verifying the integrity of files downloaded from a website. Background technique [0002] With the development of information technology, the Internet will become a comprehensive multimedia service platform integrating image, voice and data "three networks in one", and cross-integrate with e-commerce, e-government, e-official, e-medical, and e-learning. The convenience and completeness of downloading files from websites affects the use of files, especially the download of some important files. Once the file is incomplete, it will cause failure to install normally, which will affect the operation of the machine, or the file will be tampered with, which may cause risks. [0003] In the existing technology, when uploading a file, the uploader needs to manually generate the file value (such as MD5) and copy and paste it to the website, which may easily cause errors and other proble...
