Help with the hello packet

[Maik8]

hey guys,

i want to do a headless client and am not sure how the hello packet is put together.
I got this from looking into krelay, what my client sends:

BuildVersion => X33.1.0
GameId => -2
GUID => xxxxx some random string here (hash or so)
Random1 => 92446 what does this even mean? Just a random number?
Password => xxxxx some random string here aswell (hash or so)
Random2 => 67725 a second random number?
Secret => kongate secret i guess
KeyTime => -1 ?
Key => System.Byte[] what does come here?
MapJSON => leave emptry every time?
EntryTag => leave emptry every time?
GameNet => rotmg
GameNetUserId =>
PlayPlatform => rotmg
PlatformToken =>
UserToken =>
Secret2 => xxxxx some random string here aswell (hash or so)
PreviousConnectionGuid => xxxxx some ID here (important?)
Send => False
Id => 1
PacketSize => 480


How are these values from the packet put together?
Is it possible to create such a packet if i only know the login-credentials of the account? (should be).
My end-target is to have a headless client that does NOT rely on krelay or other external tools.

Any help is very appreciated!

Best regards,

Here is what i got so far, maybe someone knows a bit more and could help me with that?

BuildVersion => X33.1.0
GameId => -2
GUID => a random byte array (length:6) that is rsa encrypted with the public key from deca.
Random1 => random number between 0 and 1 * 1000000000 rounded down to the next integer.
Password => password rsa encrypted with the public key from deca.
Random2 => random number between 0 and 1 * 1000000000 rounded down to the next integer.
Secret => kongate secret i guess - still need help here
KeyTime => -1 still need help here
Key => System.Byte[] still need help here
MapJSON =>
EntryTag =>
GameNet => rotmg
GameNetUserId =>
PlayPlatform => rotmg
PlatformToken =>
UserToken => still need help here
Secret2 =>
PreviousConnectionGuid => leave blank should work (not sure tho)
Send => False
Id => 1
PacketSize => 480

GUID => a random byte array (length:6) that is rsa encrypted with the public key from deca.

guid is the email
secret needs to be left blank iirc if you don't play on kong or steam
usertoken I think was empty string
keytime,key is correct

also i think guid and pass need to be encoded in base64? maybe someone can correct me on this I think it was rsa -> base64
and I think you append this string to the hellopacket 'XTeP7hERdchV5jrBZEYNebAqDPU6tKU6' at the end unless if they changed it
