Suggested enhancement

Either a direct accessor function to retrieve the public component of an mbedtls_ecp_keypair, or a function to write out the public key to a binary buffer. Similarly, a way to create an mbedtls_ecp_keypair structure containing only the public part of the key.

Justification

Mbed TLS needs this because the public key component was made private.

Please add provider support for the "botan encryption" command and implement the needed AES operations with PKCS#11.
I could not find any command line tool that I can use for that. OpenSSL's PKCS#11 engine does not support AES either.

It would be nice to have an implementation that returns an iterator over the 4 coordinates of a RistrettoPoint or an EdwardsPoint.

Ex:

use zerocaf::edwards::EdwardsPoint;
use zerocaf::traits::Identity();
let identity = EdwardsPoint::Identity();
identity.into_iter().map(|coordinate| do_something_with_cooord(coordinate)).collect();
