These are not on track for 0.3.5, given the amount of time remaining before freeze.

Komlo said:
I see that this crate depends on several external crates. rust-crypto states that it doesn't have strong security guarantees- is there something else that we should be using? ​
Should we have an auditing process for when we choose to import/use new external crates?

nickm says:
hm. I don't think we have something else we should necessarily use yet, though probably we should make the code so it's parameterized on the crypto traits we need eventually
I think it's something we can clean up later.
I think what we want is a pattern where we have some traits, maybe copied from rust-crypto, or maybe theirs, for crypto, and we instantiate them either with a rust implementation or the Tor c implementation
looks like for this we need sha3/shake, aes, curve25519, and a time-invariant comparison

These tickets are not things I'm currently working on. They may be important, but they don't need to be done by me specifically. Un-assigning.
