NosTale-Anonymizer

A tool for NosTale packet files that filters specified packets and replaces ids, names to make the result anonymous.

Currently only files are supported. I am planning to make this work with NosSmooth.Local.

What packets are supported

Anonymizer uses NosSmooth.Packets, so all packets NosSmooth supports may be moved.

There are two filters for filtering by header and filtering text messages (;, :, /). There are some default headers that are removed, because these packets allow for identification and are not yet supported.

In case you think there is a packet that may identify anyone that is not handled,

By default, the packets that may be anonymized, are:

• at
• bs
• c_info
• c_list
• c_mode
• cond
• drop
• eq
• get
• gidx
• in
• mv
• ncif
• n_run
• out
• pairy
• pinit
• pst
• raid
• raidf
• rboss
• rdlstf
• rdlst
• revive
• say
• st
• su
• titinfo
• twk
• u_pet
• u_p
• u_s

The only things anonymized in these are ids and names. Anonymizing other things such as level, hero level, class, weapon, inventory items will be supported in the future.

Anonymization process

Anonymization happens in IAnonymizer, there is a default implementation DefaultAnonymizer that may be replaced. The default anonymizer just generates random numbers and names of length 10. It could be better to use a list of names and choose from that to make the names more user friendly.

Future features

• Add support for NosSmooth.Local. Make a deanonymizer. Anonymize the packets upon receiving and deanonymize them upon sending.
• Add support for all packets that may identify the user.
• Add support for anonymizing other things apart from id, names.
