This isn't actually wz encryption, this is merely a bug that MapleLib2 (and thus HaRepacker) has when parsing the header of wz files.
I released a patch for HaRepacker a while ago that fixes this bug making this "decryptor" redundant.
http://forum.ragezone.com/f701/release-universal-harepacker-new-version-892005/#post7585810

Also, what is with that self-destruct code?

 

[cindylim]

u have decryptor for mapleswitch?

 

[Burblish]

Lmao, since when did MapleSwitch have decrypted wz's? If, so they probably just used the read-me method.

lol....

then how i read and convert to xml for their wz?

 

[Skorch]

lol....

then how i read and convert to xml for their wz?

lol @ sango trying to steal wz edits

 

[Shinty]

If anyone needs encryptor PM me,
and also lol @ sango.

 

[AngelSpirit]

Oh god, this thread. My sides. I can't stop laughing.

 

[Mangos]

Oh god, this thread. My sides. I can't stop laughing.

I don't know why I never released this. :huh:



BoredMS is up and running now. Have fun.

Since you released the decryptor, I guess the encryptor is kind of worthless now.
So if anyone is interested, here is the encryptor(source):

Banned and demoted from BoredMS. Nothing much to do except roam around on the internet.

(Heard boredms is being leeched hardcore; kewl kewl)

New Links for BoredMS please? ((

New Links for BoredMS please? ((

y not stop leeching exe files and compile the given Encryption/Decryption sourcecode? seems pretty ez to me
