Nist256p1Signer class

Nist256p1Signer Signer class for cryptographic operations, including signing and verification.

The Nist256p1Signer class facilitates the creation of Nist256p1 signatures and provides methods for signing messages, personal messages, and converting to verification keys. It uses the ECDSA (Elliptic Curve Digital Signature Algorithm) for cryptographic operations on the secp256R1 elliptic curve.

Constructors

Nist256p1Signer.fromKeyBytes(List<int> keyBytes)
