François Garillot 29ba1b93b5 Check for small subgroup components when using the EdwardsPoint group for the OPRF 
A malicious attacker sending a small point could lead the server / user to leak private information.

The check avoiding mixed order points (rather than just small) is prohibitively expensive, and I don't know how an attacker would extract any data from that => we focus on a small order check.

Fixes #34.

François Garillot 1f8d786be8 Merge pull request #28 from huitseeker/quickfix_26 
Re-establish `cargo check --all-targets`
 2020-07-22 17:55:53 -04:00
François Garillot 8885fe5aa1 Re-establish cargo check --all-targets 
The bench in benches/oprf.rs requires a feature to have visibility over private members, and doesn't work without it.
`cargo check --all-targets` is the standard quick way to check code under build & test targets, but does not specify features.

This simply skips the `benches` when the `"bench"` feature it depends on is not activated.

Restructure password-hashing-to-the-curve as an extension trait of Group
 2020-07-03 21:10:11 -04:00
François GarillotandKevinLewi 9d40aa7659 As a way to roll back the genericity, implement an extension trait of group for password-to-curve hashing, 
This supersedes #18.

François Garillot 41cd80ccb5 Make oprf::generate_oprf1 generic in the Digest, as long as it matches the hash-to-curve intake of the group 
We used to have three problems:
- overuse of the <Sha256 as Digest>::OutputSize, which is just, well, U32. Sometimes used as a parameter (as in generate_oprf1), sometimes as a constant (as in generate_oprf3).
- the `hash_to_curve` operation for `RistrettoPoint` which requires 64 bits of input entropy, is fed 64 bits of which the last 32 are zero,
- the `hash_to_curve` operation for `Curve25519Point` which requires 32 bits of input entropy, is fed 64 bits of which the last 32 are discarded,

This corrects all three and uses U32 where the size of the digest is not meant to be a constraint.

Addresses #15 partially.

François Garillot bb9c365998 Rename Group::to_bytes() into Group::to_arr(), 
This brings the `Group` and `SizedBytes` traits into some sort of name
coherence (they both return a GenericArray). This also uses
`&my_generic_array[..]` (i.e. the `Deref` impl) over
`my_generic_array.as_slice()`.
