acesucks 1,254 Posted February 21, 2020 Report Share Posted February 21, 2020 Welcome Foreword Feel free to contribute to this thread. I hope we can bring this revision and the RSPS community as a whole to a new level by documenting as much as possible. Downloads Client Deob\Client Cache Item List (id, name) Object List (id, name) Login Breakdown Stage 0 (Client) This stage is called for disconnecting, for example when in Stage 6 a response code of 23 (No reply from loginserver) is received. Stage 1 (Client) The Client creates the connection Stage 2 (Client -> Server) The client writes 1 byte with value 14. Stage 3 (Server -> Client) The server sends 1 byte. If this byte is 0, the client proceeds to Stage 5 Stage 4 Stage 5 (Client -> Server) Part 1: Plain Data Type Value byte opcode (16/18) short login packet size int revision short RSA Block Size Part 2: RSA Encrypted Get bytes to an array the size of "RSA Block Size". Create a BigInteger from this Array. Decrypt that BigInt with modPow and wrap its ByteArray in a new ByteBuffer.

This value can be any of the following: Unexepected server responce please try using a different world. login to the game Invalid name/password banned username Account is already logged in try agian in 60 secs... Client has been updated! Please reload this page. This world is full. Please use a different world. Unable to connect. login server offline. Login limit exceeded.

You need a members account to login to this world. Please subscribe, or use a different world. Could not complete login. Please try using a different world. The server is being updated.

You have only just left another world. your profile will be transferred in xxx seconds. Malformed login packet. Please try agian. No reply from loginserver. Please wait 1minute and try again. Error loading your profile. please contact customer support. Unexepected loginserver response This computers address has been blocked as it was used to break our rules. Service unavailable. 56. Authenticator Login. As you can see this is a response to the data gathered in from Stage 5. Most of the response codes will lead to going to Stage 0 and thus disconnecting from the server. The only exceptions are: when the response code is 2, the client will immediately go to Stage 9. This is the normal flow when someone logs in 100% correctly. when the response code is 21, the client will go to Stage 7 Stage 7 (Server -> Client) When the player just left another world. The server sends a byte containing the time for the client to wait to reconnect. The client then proceeds to Stage 8 Stage 9 Data Type Description Byte Trusted Computer ?
