6.3 ECDSA Algorithm

The Elliptic Curve Digital Signature Algorithm (ECDSA) is a variation of the DSA algorithm that utilizes elliptic curves. Initially, two parties must agree on the curve parameters, which include the curve itself and its field. The Crypto v4 Library supports sign and verify ECDSA functions.

Note: When using HSM, make sure to use the Crypto_DigiSign_Ecdsa_SignData and Crypto_DigiSign_Ecdsa_VerifyData functions and pass the crypto_Hash_Algo_E parameter.
