A standard for transferring Files between airgapped units over a simplex transmission agnostic to the medium, transfer speed and distribution network. Most existing Protocols don't handle simplex transmissions at all or very poorly.

The data to be tansmitted is to be collected in a container [this may be a folder or tar archive]. The container is then optionally compressed and encrypted. The container is hashed (SHA3-512 is recommended). A header is used to communicate the essential parameters, including compression algorithm, encryption used, checksum, container size and number of fragments, timestamp, and checksum of the header.

Documentation aside, proof of concept of each feature is part of the repo in the form of shell scripts.

A wiki page that documents explanations for and origins of various types of radio broadcasts people picked up with software defined radios and analyzed with software like GQRX.
