Build Status

Create a symmetric cryptographic key in a secure, read-only Buffer

A piece in the puzzle towards secure-key-management

Usage

var createKey = require('secure-create-key')

var destroy = createKey(32, unction (err, key) {
  if (err) throw err

  // key is create-only, any writes to `key` will kill our program

  // We can use the key as a master key, and derive subkeys for eg. asymmetric purposes

  // Once we're done with the key, let's destroy it
  destroy()

  // Any further access to `key` will kill our program
})

:warning: Warnings:

  • The key is create-only. Any writes to it will crash your program with no mercy
  • Once the key is destroyed, any access to it (whether create or write) will crash your program with no mercy

API

var destroy = createKey(bytes, cb(err, secureKeyBuf))

bytes must be a safe integer at least 0, and cb must be given.

There are currenly no causes of errors, but that might change in the future

Note that the secureKeyBuf looks like a normal Buffer, but has some extra properties. You can read more about Secure Buffers on secure-key-management Be wary about using any of the default Buffer operations on this Secure Buffer.

To explicitly release the key and it's content, call the returned destroy method, which will safely wipe the key from memory and mark it for no access, to prevent any accidental misuse.

Install

npm install secure-create-key
