Code file processing method and device, code file checking method and device, and electronic equipment

The embodiment of the invention provides a code file processing method and device, a code file checking method and device, and electronic equipment. The processing method comprises the following steps: splitting function codes of at least one function in a code file into a plurality of ordered code blocks; determining prior code blocks and later code blocks forming a plurality of groups of preset mapping rules from the plurality of code blocks; and adding checking codes used for checking the prior code blocks under each preset mapping rule to the corresponding later code blocks. Correspondingly, the checking method comprises the following steps: determining at least one prior code block and at least one later code block which form the preset mapping rules from the plurality of code blocks of the code file; and based on the checking code in the at least one later code block under the preset mapping rules, checking the prior code block belonging to the same preset mapping rule. 本说明书实施例提供一种代码文件的处理方法、检验方法、装置及电子设备
