Hi! I want to present you a OOT module which provides the functionality of the NaCl crypto library for GNU Radio. The NaCl library is a well known library written by Daniel J. Bernstein, Tanja Lange and Peter Schwabe [0]. Because the library is not maintained by themselves, I have chosen the well maintained fork libsodium [1]. This fork is also used by the crypto messenger tox (awesome project! -> [2]). NaCl is also used by the messenger Threema (smartphone app).
The features of the OOT module are: Public-key en-/decryption, secret-key en-/decryption and key-pair (public/secret) or key (only secret) generation. The system is based on the message API. Furthermore, I have implemented a byte stream en-/decryption using stream ciphers. This one uses tagged streams for processing. If you are interested, you can check out the repo on GitHub [3]. In the folder examples/ are flowgraphs which explain the functionality. As well, there are unit-tests ;) So far everything works fine. I have no idea whether this is already done and I am not a crypto expert, but here it is!
