Identification method and device of messy code data, storage medium and computer equipment

Abstract

The invention discloses a messy code data identification method and device, a storage medium and computer equipment, and relates to the technical field of information. The method comprises the following steps: acquiring a character array corresponding to decrypted data to be identified; sequentially executing a judgment process on the plurality of characters according to the arrangement sequence of the plurality of characters, and for any character in the plurality of characters, judging whether the ASCII (American Standard Code for Information Interchange) corresponding to the any character is in a preset ASCII range or not; if not in the preset ASCII range, judging whether a language code corresponding to the any character is in a basic language code range corresponding to the language environment or not; if the language code is not in the basic language code range, judging whether the language code corresponding to the any character is in a supplementary language code range corresponding to the language environment; and if the decryption data is not within the supplementary language coding range, stopping executing the judgment process, and directly determining that the decryption data is messy code data.

Description

technical field [0001] The present invention relates to the field of information technology, in particular to a method, device, storage medium and computer equipment for identifying garbled data. Background technique [0002] In order to ensure the security of the transmitted data, users often encrypt the transmitted data, and other users will decrypt the encrypted data after receiving it, and the decrypted data will be displayed on the computer screen. [0003] At present, in the process of decrypting the transmitted data, even if the secret key provided by the user is wrong, the program will normally perform the decryption operation and display the garbled data to the user. However, this kind of garbled data has no meaning for the user, and the user only needs to correctly decrypt the data. This method in the prior art cannot effectively distinguish the decrypted normal data from the garbled data, so that the garbled data is provided to users, resulting in a poor user exp...
