About machine id

In Linux, machine id is a single newline-terminated, hexadecimal, 32-character, lowercase ID. When decoded from hexadecimal, this corresponds to a 16-byte/128-bit value. This ID may not be all zeros. This ID uniquely identifies the host. It should be considered "confidential", and must not be exposed in untrusted environments. And do note that the machine id can be re-generated by root.

Usage

```Rust extern crate machine_uid;

fn main() { let id: String = machine_uid::get().unwrap(); println!("{}", id); }

```

How it works

It get machine id from following source:

Linux or who use systemd:

Bash cat /var/lib/dbus/machine-id # or /etc/machine-id

BSD:

Bash cat /etc/hostid # or kenv -q smbios.system.uuid

OSX:

Bash ioreg -rd1 -c IOPlatformExpertDevice | grep IOPlatformUUID

Windows:

powershell (Get-ItemProperty -Path Registry::HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Cryptography).MachineGuid
