Elliptic Curve Digital Signature Algorithm (ECDSA) (huecc.h)
The Elliptic Curve-based digital signature algorithm (ECDSA) provides user authentication. The ECDSA functions are defined in huecc.h. The signature generation and verification must be applied to a message digest.
An ECC parameters object is required to generate or verify a signature using ECDSA. The hu_ECCParamsCreate() function creates these objects. An ECC key object is also required. An RNG context is required if key generation will be performed.
