Task #3135
Updated by Junxiao Shi over 8 years ago
ECDSA is the name of a signing algorithm using the Elliptic Curve key.
A EC key can also be used in encryptio, e.g., ECIES.
However, the abstraction for EC key parameter is named as `EcdsaKeyParams`. We need to rename it to `EcKeyParams`.
To keep backward compatibility, we still need to keep `EcdsaKeyParams` using typedef, but mark it as deprecated.
