Nexon's Private/Public Key's

[xx404xx]

Nexon's public and private key's are one step closer to discovery.Here's a algorithm and some info.With these key's we can run are own lobby's/sign files the same way nexon does.ECDSA Param's are in there,im hoping to get a P.O.C going.....

Wth is this?

[xx404xx]

The Algorithm's for code signing,and it goes hand and hand with nexon's keys.With this we could make full cheat client's,because if we can sign there file's we can make are own custom client's, and maybe even built in aimbot/hack panel's.There is still work to be done though,i still haven't found the key's but the algo is there and i am looking at older ver's for more info.We could do Private server's if we uncovered the key's.

[Skaterforeva1]

could you sum this up allot smaller cause that just omg

[[MPGH]Flengo]

Maybe make it neater next time too.

[Skaterforeva1]

Maybe make it neater next time too.

yes that would realy help

[matypatty]

maybe you could all understand it and stop complaining.... This makes a lot of sense thanks for the post!

[supercarz1991]

This is 100% leeched and Idk how the hell u got it cuz it was posted a month ago in a private Modding section on another forum

[Stevenom]

could you sum this up allot smaller cause that just omg

You can't sum up the algorithm.

This is 100% leeched and Idk how the hell u got it cuz it was posted a month ago in a private Modding section on another forum

Proof?

[Terell.]

Thank you.

[supercarz1991]

You can't sum up the algorithm.



Proof?

i was wrong, i just now realized...being on 2 forums at once where the games both have some sort of algorithm for compression and such...yeah...my bad

[Zeused]

I really don't understand what is this. Could somebody explain this to me in English.

[The Dark Knight]

no this is the C++ language section, would you care to step out? xD

[xx404xx]

PBE-MD2-DES PBE-MD5-DES
These algorithms were included in the original PKCS#5 v1.5 specification. They only offer 56 bits of protection since they both use DES.

PBE-SHA1-RC2-64 PBE-MD2-RC2-64 PBE-MD5-RC2-64 PBE-SHA1-DES
These algorithms are not mentioned in the original PKCS#5 v1.5 specification but they use the same key derivation algorithm and are supported by some software. They are mentioned in PKCS#5 v2.0. They use either 64 bit RC2 or 56 bit DES.

PBE-SHA1-RC4-128 PBE-SHA1-RC4-40 PBE-SHA1-3DES PBE-SHA1-2DES PBE-SHA1-RC2-128 PBE-SHA1-RC2-40
These algorithms use the PKCS#12 password based encryption algorithm and allow strong encryption algorithms like triple DES or 128 bit RC2 to be used.

Here is the read key command for openssl

Read a DER unencrypted PKCS#8 format private key:

openssl pkcs8 -inform DER -nocrypt -in key.der -out key.pem

Edit:There's still the Verisign problem also,unless someone happen's to find valid cert's somehow.

Edit2:Verisign has been hacked before,and im pretty sure this hash exploit is still out there that would let us generate %100 valid cert's.

Well first of all how do you think nexon does pming and thing's like that.....The Diffie-Hellman Key Exchange

Public Key
It is also possible to use Diffie–Hellman as part of a public key infrastructure. Alice's public key is simply (ga,g,p). To send her a message Bob chooses a random b, and then sends Alice gb (un-encrypted) together with the message encrypted with symmetric key (ga)b. Only Alice can decrypt the message because only she has a. A preshared public key also prevents man-in-the-middle attacks.
In practice, Diffie–Hellman is not used in this way, with RSA being the dominant public key algorithm. This is largely for historical and commercial reasons, namely that RSA created a Certificate Authority that became Verisign. Diffie–Hellman cannot be used to sign certificates, although the ElGamal and DSA signature algorithms are related to it. However, it is related to MQV, STS and the IKE component of the IPsec protocol suite for securing Internet Protocol communications.

This is not leached.This is an ECDSA fail.I also have the login token if anyone is interested.

This is how long the PKEY is usage period,self explanatory

And here it check's if it's revoked,

The end goal is to sign are own content, as you can see below

This is really interesting, good luck.
