In the previous article, the experimental environment was built. The protocol analysis can be performed once the IKE/IPSEC protocol is fully run and the relevant output and capture packets are collected. During the analysis, we will use the output of the IKE process and the Wireshark grab packet, combined with the relevant RFC, using Python to verify the calculation. First look at the full operation of the Protocol (filtering out irrelevant messages, such as)The following is a specification desc

In the past, when reading an Excel file, some fields were often read as null values. In fact, some fields were actually null values, because when reading the file, Excel would take the data type of the first row as a reference, if they are different, some problems may occur.
The following is a solution. The connection string of the Excel file is written as follows. It is said that the data can be forced to be a string. I did not test it again. For reference only.
String strconn = "provider = M
