curv exports only 1 curve implementation about curv

[survived]

Hi @omershlo! Agreed, approach in exporting 1 curve sounds reasonable at the point of security. But sometimes we have to work with several curves.

I'm interested in this change so I'd be happy to do a contribution. I'll open PR as soon as I finish the refactoring.

Hi @survived ! Thank you for raising this issue!
I completely agree,
originally, exporting only a single curve was by design: in elliptic curve cryptography applications you only need one curve and it is dangerous to work with multiple curves at the same time (if you get confused between curves even at a single operation it will have major impact on security).

Since then I realised that the above assumption is wrong (cc: @oleiba ):

• there are applications that will benefit from using multiple curves (i.e. blockchain wallets)
• Rust enables ways to protect against misuse

As you pointed out this is a significant refactor, although I have no concerns about changing dependent crates - this would be quick and painless and since we use tagging the change can be gradual.

Would you be interested championing such contribution ?
