random-access-keychain

A random-access-storage implementation which stores its contents in the system keychain. This is useful if you want to store secret keys or passwords securely.

This module should work on macOS, Linux and Windows. Check the keytar documentation for details on required dependencies on Linux.

API

var storage = randomAccessKeychain(service: string, account: string)

Implements the random-access-storage interface, ie:

• storage.write(offset: number, buffer: Buffer, callback: (err: Error) => any)
• storage.read(offset: number, size: number, callback: (err: Error, content: Buffer) => any)
• storage.del(offset: number, size: number, callback: (err: Error) => any)

Usage

var randomAccessKeychain = require('random-access-keychain')
 
var storage = randomAccessKeychain('example.com', 'harry@example.com')
storage.write(0, Buffer.from('supersecret'), err => {
  if (err) throw err
  storage.read(0, 11, (err, password) => {
    if (err) throw err
    console.log('password:', password.toString())
  })
})
