keyutils

What is this?

Go bindings for Linux's libkeyutils. libkeyutils provides an interface to the Linux kernel's keyring APIs, useful for storing secrets.

It requires headers and libs for libkeyutils to be installed, e.g. apt-get install libkeyutils-dev.

How to build and install

sudo apt-get install -y libkeyutils-dev # on ubuntu
go get github.com/jandre/keyutils

How to use

Adding and reading a key from a keyring.

See example/add_and_read_key.go to see an example of adding and reading a key from the user keyring.

For other examples, please see example/.

package main

import (
	"log"

	"github.com/jandre/keyutils"
)

func main() {
	id, err := keyutils.AddKey(keyutils.USER, "test123", "hello", keyutils.KEY_SPEC_USER_KEYRING)

	if err != nil {
		log.Fatal("Error adding key:", err)
	}
	log.Println("Added key test123 with serial:", id)
	val, err := keyutils.ReadKey(id)

	if err != nil {
		log.Fatal("Error reading key:", err)
	}

	log.Println("Read:", val)
}

$ go run example/main.go
