README

dsigner

A set of tools to support digtially signing and verifying messages.

Installation

npm install -g dsigner

Usage

In all cases, the keys to be used are assumed to be located in the 'keyBaseDir' directory and are named "_(public|private).pem" (e.g. bob_private.pem).

var dsigner = require('dsigner')

var keyBaseDir = "/etc/pki/keys";
var theMessage = "The message to be signed";

var signature = dsigner.signMessageFor(keyBaseDir, 'bob', theMessage);

var valid = dsigner.verifyMessageFor(keyBaseDir, 'bob', theMessage, signature);

Also provided are two executables that allow you to sign/verify messages:

$ sign_message bob "the message to sign"
  <the signature>

$ verify_message bob "the message to sign" <the signature>
  true or false

The location of the key for the programs is determined by the value of the KEY_PATH environment variable.
