Usage
require "cox"
data = "Hello World!"
# Alice is the sender
alice = Cox::KeyPair.new
# Bob is the recipient
bob = Cox::KeyPair.new
# Encrypt a message for Bob using his public key, signing it with Alice's
# secret key
nonce, encrypted = Cox.encrypt(data, bob.public, alice.secret)
# Decrypt the message using Bob's secret key, and verify its signature against
# Alice's public key
decrypted = Cox.decrypt(encrypted, nonce, alice.public, bob.secret)
String.new(decrypted) # => "Hello World!"
