Missing protocols

[newpavlov]

List of "would be nice to have" protocols:

• [x] AuCPace (#115)
• [ ] Dragonfly (see also: Dragonblood attack)
• [ ] CHIP
• [ ] CRISP
• [ ] OPAQUE
• [x] SPAKE2 (#3)
• [ ] SPAKE2+

Spake2 (but not Spake2+) has now moved in, from https://github.com/warner/spake2.rs .

OPAQUE would be pretty cool. Like most of these protocols, though, the paper doesn't specify a group to use or encoding formats, so we'll have to make up some standards ourselves. Has anyone seen other implementations yet? We should coordinate with those to converge on a shared layout.

I implemented a simple OPAQUE prototype.

@quininer Are you interested into devellopping it further and maintaining it? Else, there is also that crate that popped up not too long ago and seems to be well maintained and documented: https://github.com/novifinancial/opaque-ke

@zer0x64 I never planned to release it as a crate, and when I made it, opaque did not have any standards, so I think it is good to have a new implementation.
