Did the GMS Packet Encryption Change? [Yes]

[alonevampire]

Did something in MapleStory's encryption change as of v118?
MapleShark (among other things) prints gibberish decrypted packets when connecting to v118 MapleStory, and since MapleShark isn't throwing any errors due to invalid prefix headers I assume it's not at the fault of the IV's or versions. Maybe the AES key changed, or MapleStory changed their custom encryption/added a new one.

Anyone else know about this? Is this only happening to me? Does anyone know what Nexon did?

They indeed change the encryption(keys). I hope to retrieve it this evening

Yep, although they needed 10 hours for fixing 2 things

It's already "gotten". It's a bit tricky but honestly wasn't as hard as I thought they were going to make it.

Pardon the fail OP codes as I haven't updated them.

Re: Did the GMS Packet Encryption Change?

interesting. oh well, not completely screwed anyways since can always just log sendpacket and processpacket within the client its self
good thing i'm not working on v118 so i don't have to deal with this crap

I have dumped the memory and it seems like the keys are all the same.. O_O
I must've missed something.. or I don't know..

Re: Did the GMS Packet Encryption Change?

Wouldn't the BMS MapleShark here work for it, since all GMS did was revert to an older encryption I thought?

Nope, we tried all the known encryptions.

Nope, we tried all the known encryptions.

I don't think it one of the keys because the client still holds the previous keys..
I think it's a new encryption and decryption method.
or maybe something really small that we are missing.

What's that supposed to mean, mister?

Re: Did the GMS Packet Encryption Change?

So did the keys change or did something else change?

well Nexon took this long to do?? nuts

it seems that no one here remember who you are the same guy who coded Guilds for odin back development in the days remember you thought like the other developers you left for good..

I can tell you it's been cracked by us already; it has changed more than you know.

If you know who cracked it, sharing is caring. Or not because either way stuff gets leaked soon or later.

I'm not sure what you have against sharing the updated MS Packet Encryption.

You are not the only who's realized that. I've been here since 08 despite the account creation date. Extalia's got the v118 encryption.
