Configuration

When ServerOfflineAuth is first started, it creates the server_offline_auth-common.toml file in the config/ directory with the following content:

#Server Offline Auth Configuration
[general]
    #Login timeout (seconds), set to 0 to disable
    #Range: 0 ~ 3600
    loginTimeout = 30
    #Salt length (log rounds). Default 10, range 4-30.
    #Range: 4 ~ 30
    passwordHashWorkFactor = 10
    #Player data file name (only effective when storage type is json)
    dataFileName = "server_offline_auth_data.json"
    #Whether to send a prompt when a player joins
    joinMessageEnabled = true

[storage]
    #Data storage type: json or mysql
    storageType = "json"
    #MySQL host address
    mysqlHost = "localhost"
    #MySQL port
    #Range: 1 ~ 65535
    mysqlPort = 3306
    #MySQL database name
    mysqlDatabase = "ServerOfflineAuth"
    #MySQL username
    mysqlUsername = "root"
    #MySQL password
    mysqlPassword = "password"
    #MySQL table name
    mysqlTable = "auth_players"
    #Token validity days (0 means never expires)
    #Range: 0 ~ 3650
    tokenExpiryDays = 3

[storage.migration]
    #Set this to perform data migration (e.g., "mysql" or "json"). After successful migration, this value will be automatically cleared, and storageType will be updated.
    migrateTo = ""

If the data storage mode is JSON, a file named server_offline_auth_data.json will be created in the server root directory to store player data.
If the data storage mode is MySQL, you need to ensure that the MySQL server is properly configured and running, and that the provided connection information is correct.
The server-side tokens are stored in the server_offline_auth_tokens.json file under the config/ folder.
