cloak is a utility to share senstive details like passwords, API tokens or any other secret text to a recipient. It encrypts the message with a strong XSalsa20 cipher on client side.
The key to decrypt is never stored with the backend, ensuring that only the recipient who has the link can decrypt it. An additional passphrase is required by the user to be set, which ensures that even if the key leaks, only the designated recipient can view the secret.

See docker-compose.yml for an example.
