Encryption

1. Compiling the verysecure module
   • Setup build environment (Debian)
     • sudo apt install build-essential npm nodejs
     • sudo npm install -g node-gyp
   • Install node-gyp:
     • npm install -g node-gyp
   • Change directory:
     • cd /path/to/CSE4471/encryption
   • Build module:
     • node-gyp configure; node-gyp build
   • Relocate module:
     • File is ./build/Release/verysecure.node
2. Using the verysecure module:

const crypto = require('./verysecure');

function encrypt(data, key){
  var txt = Buffer.from(data,'ascii');
  return crypto.encrypt(txt, key).toString('hex');
}

function decrypt(data, key){
  var ctxt = Buffer.from(data,'hex');
  return crypto.decrypt(ctxt, key).toString('ascii');
}
