Header
Login messages have a header of 1 byte with an opcode. Some messages also have a size field but this is not considered part of the header.
Login Header
| Offset | Size / Endianness | Type | Name | Description |
|---|---|---|---|---|
| 0x00 | 1 / - | uint8 | opcode | Opcode that determines which fields the message contains. |
Body
| Offset | Size / Endianness | Type | Name | Comment |
|---|---|---|---|---|
| 0x01 | 1 / - | u8 | protocol_version | Mangos statically sets this to 0. It is unknown exactly what it does. |
| 0x02 | 1 / - | LoginResult | result |
If result is equal to SUCCESS:
| Offset | Size / Endianness | Type | Name | Comment |
|---|---|---|---|---|
| 0x03 | 32 / - | u8[32] | server_public_key | |
| 0x23 | 1 / - | u8 | generator_length | The only realistic values for the generator are well below 255, so there's no reason for this to anything other than 1. |
| 0x24 | ? / - | u8[generator_length] | generator | |
| - | 1 / - | u8 | large_safe_prime_length | Client can not handle arrays greater than 32. |
| - | ? / - | u8[large_safe_prime_length] | large_safe_prime | |
| - | 32 / - | u8[32] | salt | |
| - | 16 / - | u8[16] | crc_salt | Used for the crc_hash in CMD_AUTH_LOGON_PROOF_Client. |
