QuantumKryptonite is a post quantum public key cryptography app. It facilitates secure file transfer between 2 parties by generating the keys and files to be exchanged, including the encrypted file the 2 parties want to share. It is resistant to being broken by current technology and is future-proof against upcoming quantum computers. Symmetric encryption keys are exchanged using either of 2 algorithms: QuaKKE (QuantumKryptonite Key Exchange) or LWE (Learning With Errors). Once symmetric keys have been securely exchanged, there is also an option to re-use symmetric encryption keys.
