ImportError: cannot import name 'sign', 'verify' #58
Description
from pycoin.ecdsa import generator_secp256k1, sign, verify
import hashlib, secrets
def sha3_256Hash(msg):
hashBytes = hashlib.sha3_256(msg.encode("utf8")).digest()
return int.from_bytes(hashBytes, byteorder="big")
def signECDSAsecp256k1(msg, privKey):
msgHash = sha3_256Hash(msg)
signature = sign(generator_secp256k1, privKey, msgHash)
return signature
def verifyECDSAsecp256k1(msg, signature, pubKey):
msgHash = sha3_256Hash(msg)
valid = verify(generator_secp256k1, pubKey, msgHash, signature)
return valid
i think the example code is broken or outdated. i cant import sign or verify at all
