Returns the PublicKey instances recovered from the given signature and KeyAPI.ecdsa_recover(message_hash, signature) -> PublicKey public_key: must be an instance of PublicKey.signature: must be an instance of Signature.Signature for the provided message_hash and public_key. Returns True or False based on whether the provided signature is a valid KeyAPI.ecdsa_verify(message_hash, signature, public_key) -> bool private_key: must be an instance of PrivateKey.message_hash: must be a byte string of length 32.This method returns a signature for the given message_hash, signed by the environ = 'eth_' KeyAPI.ecdsa_sign(message_hash, private_key) -> Signature String with the dot-separated import path for the backend class.

The backend argument can be given in any of the following forms. Note: The coincurve library is not automatically installed with eth-keys and must be installed separately. eth_: Uses the coincurve library for ECC operations.īy default, eth-keys will try to use the CoinCurveECCBackend,įalling back to the NativeECCBackend if the coincurve library is not.eth_: A pure python implementation of the ECC operations.The object takes a single optional argument in its constructor whichĭesignates what backend will be used for eliptical curve cryptography The KeyAPI object is the primary API for interacting with the eth-keys public_key True Documentation KeyAPI(backend=None) recover_public_key_from_msg( b'a message') = pk.
