Nothing is anything. We're all just subatomic particles destined for heat death

But, really:

openpgpjs, the topic of the article, is a program that implements the OpenPGP standard, and the cryptographic algorithms it depends on.

node-gpg, the topic of this comment, does not implement any part of the OpenPGP standard, nor any cryptographic algorithms. It executes a local C program, GnuPG. If you don't have that C program, it does nothing.

Suggesting that they are the same thing is silly. The distinction is massive.

Otherwise, I could claim I just implemented a world-class PGP implementation! To try it out, just run: perl -e "exec 'gpg'"
