#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.
