Implement hash to group element #2

Open isislovecruft opened 5 years ago

I've not implemented hash-to-group yet. https://ristretto.group/formulas/elligator.html

Can libsodium be used? https://download.libsodium.org/doc/advanced/point-arithmetic/ristretto#hash-to-point-elligator

@Warchant No, libsodium cannot be used, as that would defeat the purpose of implementing this on top of ed25519-donna.

I've started this work in my feature/ristretto-from-uniform-bytes branch, which has our flavour of the elligator2 encoding and a ristretto_from_uniform_bytes() wrapper API on top of it.
