Get os native machine id without root permission.
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.
Please note that on *nix platforms, this library does not require any dependencies,
but on Windows, it requires the winreg dependency. So if you only need to build the *nix version,
you can use version 0.3.0.
```Rust use machine_uid;
fn main() { let id: String = machine_uid::get().unwrap(); println!("{}", id); }
```
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
I have tested in following platform:
