Emulating it requires ECDSA support in the crypto akcipher framework, which today only implements RSA. Introduce a new asymmetric cipher algorithm, ECDSA, a curve identifier enum (prime256v1 / NIST P-256 and secp384r1 / NIST P-384) and the per-algorithm ECDSA options. This is the QAPI groundwork consumed by the crypto akcipher backends in the following patches. Signed-off-by: Jamin Lin Acked-by: Markus Armbruster Reviewed-by: Daniel P.
