SubstrateEcdsaSigner class

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

The ETHSigner class facilitates the creation of Ethereum 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 secp256k1 elliptic curve.

Methods

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

sign(List<int> digest, {bool hashMessage = true}) → List<int>

Signs a personal message digest with an optional payload length.

override
