Is Perfect Forward Secrecy (PFS) within the scope of Okam?

[taqtiqa-mark]

If so are there any tutorials or blog posts showing how to use Okam for PFS?

Hi @taqtiqa-mark, yes.

Ockam Secure Channels are described in detail here.
https://docs.ockam.io/reference/protocols/secure-channels

The Authenticated Key Establishment part of our Secure Channels is based on the XX handshake design pattern as described in the Noise Protocol Framework. Application data, that travels over channels established in this way, benefits from strong forward secrecy. This was formally modeled and verified in the following paper by Benjamin Dowling, Paul Rösler, and Jörg Schwenk: https://eprint.iacr.org/2019/436.pdf

There are lots of examples on how to use Ockam in our docs. Is there a specific use case that you would like to apply it to? If you would prefer to discuss it in private you can reach me at mrinal@ockam.io

Ockam can be used as a command line or as a programming library.

Thanks @mrinalwadhwa, "Noise protocol" is what I should have been searching for.

Is there a specific use case that you would like to apply it to?

I have a speculative use case for a blockchain smart contract communicating with an off chain worker. I'll read the Smart Channel docs and return with any wrinkles or questions.
