Crypto

aes_gcm bindings for lulu.

Methods

• crypto.encrypt(key, nonce, data: ByteArray): Returns an encrypted ByteArray of supplied data.
• crypto.encrypt(key, nonce, data: ByteArray): Decrypts a provided encrypted ByteArray.
• crypto.random_key(size): Provides a ByteArray of a key.
• crypto.random_nonce(size): Provides a ByteArray of a nonce.

using { lulib.crypto }

local key = crypto.random_key()
local nonce = crypto.random_nonce()

local entity = ByteArray("Data")

local encrypted = crypto.encrypt(key, nonce, entity)

local decrypted = try!
  return Ok(crypto.decrypt(key, nonce, encrypted));

match(decrypted) do
  if Err then
    print("Decryption Failed")
  if Ok then
    local res = decrypted.unwrap():to_string()
    print("Result: \"" .. res .. "\"")
end
