WebElliptic Curve Digital Signature Algorithm or ECDSA is a cryptographic algorithm used by Bitcoin to ensure that funds can only be spent by their rightful owners. It is dependent on the curve order and hash function used. For bitcoin these are Secp256k1 and SHA256 (SHA256 ()) respectively. private key: A secret number, known only to the person ... WebA random Elliptic Curve Cryptography (ECC) key pair is generated and imported into the PSA crypto keystore. The public key of the ECDSA key pair is imported into the PSA crypto keystore. ECDSA signing and verification: Signing is performed using the private key of the ECC key pair. The signature is verified using the exported public key.
