How to access new key files in the SSH preferences.

Hi all,

I would like to decrypt SSH using Wireshark. For this purpose, I want to add four new fields in the class packet-ssh.c in the function proto_register_ssh(void). Using, for example, the function prefs_register_string_preference(). My question is now. After the user has entered these keys in the new fields, pressed "Ok" and started the capturing of SSH packets, how can I get the entered values later on for example in the ssh_dissect_ssh2() function in packet-ssh.c class? Thanks a lot in advance!

Looking at chapter 2.6 of README.dissector in the doc directory of your source tree, you'll see that the function prefs_register_string_preference() takes as the last parameter a char pointer pointer. This is where the entered preference ends up. Have a look at other dissectors which use this same function to see how that's used.

Look at the User Preferences section (2.6) in README.dissector.

Basically when you register the preference you pass a pointer to a static variable in your dissector and this is updated with the new value.
