Abstract

The embodiment of the invention provides a type identification method and device of coded data, electronic equipment and a storage medium. The type identification method of the coded data comprises the steps that byte data of the coded data are acquired; obtaining statistical characteristics of the byte data; and obtaining a coding type corresponding to the byte data according to the statistical characteristics of the byte data. In the embodiment of the invention, the coding type of the data is identified according to the statistical characteristics of the byte data, and different coding methods have different matching modes and conversion modes for the original data, so that the statistical characteristics of the byte data are different, and the statistical characteristics are relatively stable characteristics for the byte data; the coding type corresponding to the byte data is obtained through the statistical characteristics of the byte data, so that the method is more accurate compared with a matching rule-based identification method in the prior art, and the accuracy of coding type identification can be improved.

Description

technical field [0001] The present application relates to the technical field of encoded data processing, and in particular, relates to an encoded data type method, device, electronic device, and computer-readable storage medium. Background technique [0002] When transmitting a byte sequence in the network, in order to make the byte sequence be processed by different types of network devices, it is usually necessary to encode the byte as a string, and the Base series of encoding methods are widely adopted. Base series encoding methods include: Base16, Base32, Base58, Base64, Base85, Base91, etc. It is very important for network data analysis to accurately identify the encoding method adopted by the byte sequence. Most of the existing methods for identifying Base series codes are based on certain matching rules. For example, the rules for identifying Base64 encoded data: the string may only contain A-Z, a-z, 0-9, +, / , = characters; the length of the string is a multiple o...
