Abstract

The invention discloses a data communication coding and decoding method. The method comprises following steps of step 1, making a mapping table, thus enabling binary byte data to be mapped to visible text characters, wherein the text characters are a set of ASCII characters; step 2, obtaining binary data of data needing to communicate; and converting binary data of any one byte into corresponding Base64 coding text characters. According to the method, the binary data is coded in a fixed length mode; therefore, the length of the original data is easy to obtain through base64 coding; and analysis is very convenient, therefore, it is very beneficial for the calculation of a computer processor.

Description

technical field [0001] The invention belongs to the field of computer communication, in particular to a data communication encoding and decoding method. Background technique [0002] Base64 is an encoding popular for the transmission of binary information on the Internet. It can convert binary byte data that cannot be displayed into visible text byte data. Since many public network protocols need to transmit visible text characters, it is necessary to convert some binary data (such as images and audio data) into visible text data for transmission and exchange. [0003] There are two problems in the existing Base64 encoding and decoding methods. [0004] First, the standard is completely open, so if some hackers know that the current data is encoded in Base64, they can easily obtain the corresponding original data information. [0005] Secondly, dealing with the existing encoding method is not friendly to the processor, because it needs to look back two bytes to determine ...
