Details

Summary

Depends on D3578

Implementation of the CipherSuite trait, which configures the underlying primitives for OPAQUE.

  • Group: a finite cyclic group along with a point representation, along with an extension trait PasswordToCurve that allows some customization on how to hash a password to a curve point
  • KeyExchange: The key exchange protocol to use in the login step
  • Hash: The main hashing function to use
  • SlowHash: A slow hashing function, typically used for password hashing
Test Plan

cargo build

this will get tested more in subsequent diffs that use the CipherSuite

Adding @anunayk and making @jimpo since it appears like there are some cryptography decisions to be made here

expose OPAQUE's CipherSuite as a library instead of a module, so that it can be reused in another executable to generate a keypair for the server
