About
In an age of quantum computing, we must have a way of securing our important messages against quantum computers. This Chrome extension was developed to try and fill this need, by allowing you to easily encrypt your important messages with one time pad encryption, an encryption algorithm that cannot be broken by quantum computers. Along with this, we also use SHA-512 to ensure integrity of your messages.
