Hi,


Recently I’ve started investigating the requirement for FIPS [1] compliance with kata containers, currently
it doesn’t seem there's much cryptography happening in Kata, however, it was brought to my attention
that it might be more common in the confidential computing solutions.
As the requirement for FIPS compliance is sometimes correlated to dealing with sensitive information I
tend to believe it might also be a requirement by some of the confidential computing users.

Since I’m jumping a bit late on the confidential computing train \o/ I’d like to ask some newbie questions:

* Was FIPS compliance discussed/considered in the context of confidential computing?

Not that I recall

* Is it known already what crypto components are expected to be used?

The ones I heard mentioned are:

- ocicrypt (https://github.com/containers/ocicrypt) and ocicrypt-rs (https://github.com/containers/ocicrypt-rs) for attestation
- LUKS for volumes
- TLS / HTTPS when communicating from the container
- ssh to talk to the container itself

* I saw it’s planned to re-implement the ocicrypt library in Rust[2], AFAIU Rust doesn’t have standard library
  cryptography, hence, i assume it will count on all sorts of other crypto dependencies, is there any plan to
  have limitations/requirements on what should be used?

Not that I am aware of.

I'm not a FIPS nor crypto expert, however I'd be glad to help or provide more info if required :)

Regards,
Snir.
