Abstract
Systems and methods for encrypting a dataset are provided. The methods may include deriving an ephemeral key, and encrypting the dataset using the ephemeral key to produce a ciphertext. The ephemeral key, without being saved after the encrypting, may be re-derivable on demand and operable to decrypt the ciphertext.
