Future of Datamining 0 Comments
On 2025-12-04 gravity added a new encryption method for grf files. They also encrypted the patch files and gave them a new extension
- .gef
- .gsf
When patching the data.grf these files are not extracted and put into the target but copied directly. So the Patch Client does not know how to decrypt these files. Gravity also tried to initialize the encryption key with the `AC_ACCEPT_LOGIN` with the result that you can't open replays anymore because the decryption is not initialized - they reverted at least that part.
Due to this, you can't see those new formatted file in GRF Editor anymore - for the current kRO data.grf it's
- data\LuaFiles514\Lua Files\EffectTool\prontera.lub
- data\prontera.gat
- data\prontera.rsw
- data\prontera.gnd
These files are in the data.grf file table but the file is not visible - and the data is broken. They prepared that for a pretty long time (starting to appear in the client on 2025-03-19) and will start using it with the next patch which introduces the new job class druid. They don't want private servers to use their files with the sideeffect that even fansites can't get their information anymore.
They support multiple types of encryptions
- GOST
- IDEA
- OFB
- RC5
- RC6
- TEA
- ThreeWay
- XTEA
This means that datamining won't be possible for those files until the encryption is implemented.
