Hello, I’m new here and also new to developing a Pangya server, and I’d like some advice from you guys. What software can I use to check the client packages and decrypt them? How can I understand this data? Taking a look at the files available on the internet, can I make use of some data from AcrisioSS server for seasons 2 and 3? Thank you. 
Hi and welcome!
WireShark is usually used and then some external tool to decrypt the .pcap packets, unfortunately I don’t know more.
Are you planning to open a S2/S3 server?
