GPG Encryption/Decryption in Node.js
This module is a wrapper around gpg for use within Node. Node-GPG takes care of spawning gpg, passing it
the correct arguments, and piping input to stdin. It can also pipe input in from files and output out to files.
Use Node-GPG if you are considering calling gpg directly from your application.
Requirements
In order to use Node-GPG, you'll need to have the gpg binary in your $PATH.
Installation
npm install gpg
Usage
Node-GPG supports both direct calls to GPG with string arguments, and streaming calls for piping input and output from/to files.
See the source for more details.
If a function you need is not implemented, you can call gpg directly with arguments of your choice by
calling gpg.call(stdinStr, argsArray, cb), or gpg.callStreaming(inputFileName, outputFileName, argsArray, cb).
Notes
Existing implementations of PGP in Javascript are blocking and unfeasibly slow for server use.
In casual testing, encrypting a simple 400-character email to an El-Gamal key took upwards of 11 seconds using
openpgpjs and 14 seconds with kbpgp,
but takes less than 0.1 seconds with gpg directly.
