# machineid provides support for reading the unique machine id of most host OS's (without admin privileges)
|
||||
|
||||
|
||||
|
||||
… because sometimes you just need to reliably identify your machines.
|
||||
|
||||
[](https://godoc.org/github.com/denisbrodbeck/machineid) [](https://goreportcard.com/report/github.com/denisbrodbeck/machineid)
|
||||
|
||||
## Main Features
|
||||
|
||||
* Cross-Platform (tested on Win7+, Debian 8+, Ubuntu 14.04+, OS X 10.6+, FreeBSD 11+)
|
||||
* No admin privileges required
|
||||
* Hardware independent (no usage of MAC, BIOS or CPU — those are too unreliable, especially in a VM environment)
|
||||
* IDs are unique<sup>[1](#unique-key-reliability)</sup> to the installed OS
|
||||
|
||||
## Installation
|
||||
|
||||
Get the library with
|
||||
|
||||
```bash
|
||||
go get github.com/denisbrodbeck/machineid
|
||||
```
|
||||
|
||||
You can also add the cli app directly to your `$GOPATH/bin` with
|
||||
|
||||
```bash
|
||||
go get github.com/denisbrodbeck/machineid/cmd/machineid
|
||||
```
|
||||
|
||||
## Usage
|
||||
|
||||
```golang
|
||||
package main
|
||||
|
||||
import (
|
||||
"fmt"
|
||||
"log"
|
||||
"github.com/denisbrodbeck/machineid"
|
||||
)
|
||||
|
||||
func main() {
|
||||
id, err := machineid.ID()
|
||||
if err != nil {
|
||||
log.Fatal(err)
|
||||
}
|
||||
fmt.Println(id)
|
||||
}
|
||||
```
|
||||
|
||||
Or even better, use securely hashed machine IDs:
|
||||
|
||||
```golang
|
||||
package main
|
||||
|
||||
import (
|
||||
"fmt"
|
||||
"log"
|
||||
"github.com/denisbrodbeck/machineid"
|
||||
)
|
||||
|
||||
func main() {
|
||||
id, err := machineid.ProtectedID("myAppName")
|
||||
if err != nil {
|
||||
log.Fatal(err)
|
||||
}
|
||||
fmt.Println(id)
|
||||
}
|
||||
```
|
||||
|
||||
### Function: ID() (string, error)
|
||||
|
||||
Returns original machine id as a `string`.
|
||||
|
||||
### Function: ProtectedID(appID string) (string, error)
|
||||
|
||||
Returns hashed version of the machine ID as a `string`. The hash is generated in a cryptographically secure way, using a fixed, application-specific key (calculates HMAC-SHA256 of the app ID, keyed by the machine ID).
|
||||
|
||||
## What you get
|
||||
|
||||
This package returns the OS native machine UUID/GUID, which the OS uses for internal needs.
|
||||
|
||||
All machine IDs are usually generated during system installation and stay constant for all subsequent boots.
|
||||
|
||||
The following sources are used:
|
||||
|
||||
* **BSD** uses `/etc/hostid` and `smbios.system.uuid` as a fallback
|
||||
* **Linux** uses `/var/lib/dbus/machine-id` ([man](http://man7.org/linux/man-pages/man5/machine-id.5.html))
|
||||
* **OS X** uses `IOPlatformUUID`
|
||||
* **Windows** uses the `MachineGuid` from `HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Cryptography`
|
||||
|
||||
## Unique Key Reliability
|
||||
|
||||
Do note, that `machine-id` and `MachineGuid` can be changed by root/admin, although that may not come without cost (broken system services and more).
|
||||
Most IDs won't be regenerated by the OS, when you clone/image/restore a particular OS installation. This is a well known issue with cloned windows installs (not using the official sysprep tools).
|
||||
|
||||
**Linux** users can generate a new id with `dbus-uuidgen` and put the id into `/var/lib/dbus/machine-id` and `/etc/machine-id`.
|
||||
**Windows** users can use the `sysprep` [toolchain](https://docs.microsoft.com/en-us/windows-hardware/manufacture/desktop/sysprep--generalize--a-windows-installation) to create images, which produce valid images ready for distribution. Such images produce a new unique machine ID on each deployment.
|
||||
|
||||
## Security Considerations
|
||||
|
||||
A machine ID uniquely identifies the host. Therefore it should be considered "confidential", and must not be exposed in untrusted environments. If you need a stable unique identifier for your app, do not use the machine ID directly.
|
||||
|
||||
> A reliable solution is to hash the machine ID in a cryptographically secure way, using a fixed, application-specific key.
|
||||
|
||||
That way the ID will be properly unique, and derived in a constant way from the machine ID but there will be no way to retrieve the original machine ID from the application-specific one.
|
||||
|
||||
Do something along these lines:
|
||||
|
||||
```golang
|
||||
package main
|
||||
|
||||
import (
|
||||
"crypto/hmac"
|
||||
"crypto/sha256"
|
||||
"fmt"
|
||||
"github.com/denisbrodbeck/machineid"
|
||||
)
|
||||
|
||||
const appKey = "WowSuchNiceApp"
|
||||
|
||||
func main() {
|
||||
id, _ := machineid.ID()
|
||||
fmt.Println(protect(appKey, id))
|
||||
// Output: dbabdb7baa54845f9bec96e2e8a87be2d01794c66fdebac3df7edd857f3d9f97
|
||||
}
|
||||
|
||||
func protect(appID, id string) string {
|
||||
mac := hmac.New(sha256.New, []byte(id))
|
||||
mac.Write([]byte(appID))
|
||||
return fmt.Sprintf("%x", mac.Sum(nil))
|
||||
}
|
||||
```
|
||||
|
||||
Or simply use the convenience API call:
|
||||
|
||||
```golang
|
||||
hashedID, err := machineid.ProtectedID("myAppName")
|
||||
```
|
||||
|
||||
## Snippets
|
||||
|
||||
Don't want to download code, and just need a way to get the data by yourself?
|
||||
|
||||
BSD:
|
||||
|
||||
```bash
|
||||
cat /etc/hostid
|
||||
# or (might be empty)
|
||||
kenv -q smbios.system.uuid
|
||||
```
|
||||
|
||||
Linux:
|
||||
|
||||
```bash
|
||||
cat /var/lib/dbus/machine-id
|
||||
# or when not found (e.g. Fedora 20)
|
||||
cat /etc/machine-id
|
||||
```
|
||||
|
||||
OS X:
|
||||
|
||||
```bash
|
||||
ioreg -rd1 -c IOPlatformExpertDevice | grep IOPlatformUUID
|
||||
```
|
||||
|
||||
Windows:
|
||||
|
||||
```batch
|
||||
reg query HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Cryptography /v MachineGuid
|
||||
```
|
||||
or
|
||||
* Open Windows Registry via `regedit`
|
||||
* Navigate to `HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Cryptography`
|
||||
* Take value of key `MachineGuid`
