Usage

config.json
{
    "http_addr": "localhost:8964",      // http service port
    "folder": "./temp",                 // local directory to be mapped
    "fs_type": "xor",                   // filesystem type
    "fs_param": {                       // filesystem parameters, i.e. security key
        "key": "qwertyuiop[]" 
    }
}

./coffer [-c config] [-l log]

• -c config, configuration file to be used, default is config.json
• -l log log file, default is coffer.log

After the utility is launched, use explorer under Windows, Finder under MacOS, to map the URL to local directory. For example, map http://localhost:8964 as configured like above. Then the filesystem can be used.
