Abstract

The invention provides an encoding and decoding method of a two-dimensional code, which comprises the following steps: S1, converting a character string including information to be encoded into an initial byte array, S2, encrypting the initial byte array to generate an encrypted byte array, and S3, converting the encrypted byte array into a character string including two-dimensional code information. The encoding and decoding method of the two-dimensional code can improve safety of the two-dimensional code.

Description

technical field [0001] The invention relates to the field of encryption and decryption, in particular to a two-dimensional code encoding and decoding method. Background technique [0002] A two-dimensional code is a barcode that uses a specific geometric figure to record data symbol information in a black and white pattern distributed in a plane (two-dimensional direction) according to a certain rule. QR code is a kind of DOI (Digital Object Unique Identifier, digital object unique identifier). QR codes are a more advanced barcode format than 1D codes. One-dimensional codes can only express information in one direction, while two-dimensional codes can store information in both horizontal and vertical directions. One-dimensional codes can only be composed of numbers and letters, while two-dimensional codes can store information such as Chinese characters, numbers and pictures, so the application fields of two-dimensional codes are much wider. [0003] In the coding, the co...
