Overview
Two shell scripts intended to save and restore LUKS critical data (such as header and master key) in safe manner.
In details that means that LUKS header and master key are protected by several hash sums, then are packed and
encrypted with AES-256 (OFB). Encrypted tarball then gets additional protection using several recovery volumes.
This last step is optional and is performed only if utility par2 is found on the host.
