Embodiment Construction

[0031] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are the Some, but not all, embodiments are invented. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

Abstract

The embodiment of the invention discloses a file decryption method and device. A secret key used for decryption is pre-stored in a secret key set configured in a decryption server. The decryption server can schedule the secret key of a file to be decrypted from the secret key set according to the file identifier of the file to be decrypted when the batch file decryption process is performed in the bid opening link, and the file to be decrypted is decrypted so that file decryption of the bid opening link does not depend on participation of client sides, unified file decryption is performed through the decryption server directly and thus the file decryption efficiency of the bid opening link can be greatly enhanced.

Description

technical field [0001] The invention relates to the field of data processing, in particular to a file decryption method and device. Background technique [0002] In the traditional bidding process, suppliers will provide corresponding bidding documents. The bidding documents are encrypted files, and the bidding documents can only be decrypted when entering the bid opening link. [0003] When it is necessary to decrypt the bidding documents, the traditional method is that the supplier inserts the electronic key on the client side, obtains the key after passing the verification on the server side, and then the supplier enters the electronic key password on the client side again, calls the supplier’s private key, Decrypt the encryption key, and then use the decrypted key to decrypt the tender document on the server side. It can be seen that the decryption of a bidding document requires the supplier to plug and unplug the electronic key several times. [0004] Generally speak...
