Parameters: signature: The ECDSA signature. message: The message that was supposedly signed. public_key: The formatted public key. hasher (collections.abc.Callable[[bytes], bytes] | None): The hash function to use, which must return 32 bytes. By default, the `sha256` algorithm is used. If `None`, no hashing occurs. context: The secp256k1 context. Returns: A boolean indicating whether or not the signature is correct. Raises: ValueError: If the public key could not be parsed or was invalid, the message hash was not 32 bytes long, or the DER-encoded signature could not be parsed. zsecp256k1_pubkey *z1The public key could not be parsed or is invalid.Nz#Message hash must be 32 bytes long.zsecp256k1_ecdsa_signature *z.The DER-encoded signature could not be parsed.) r newr secp256k1_ec_pubkey_parsectxr5ro MSG_HASH_SIZE#secp256k1_ecdsa_signature_parse_dersecp256k1_ecdsa_verify) rrrsrtrurvpubkey pubkey_parsedrpmsg_hashsig sig_parsedverifieds rverify_signatureres,W) * *F1'+vzSVWaSbSbccM Aoo"("4vvg'H 8}} %%3oo '/ 0 0C8c9VYZcVdVdeeJ >oo)'+sHfMMH| rNr0)r1r!rr!)rrrr8)r=r8rr)r1r!rr)rLrrMr8rrN)rVrrr)r^rrr)rr)rjrrr)rhrrr) rrrrsrrtrrurrvr rrw)0 __future__rbase64rrhashlibrrosrrtypingr coincurve._libsecp256k1r r coincurve.contextr r collections.abcrcoincurve.typesrrgrnrer|rfr[r\getNULL DEFAULT_NONCEtupler r,r7r<rErHrKrUr]rcrirGrqrr#rrrs""""""''''''''%%%%%% ,,,,,,,,55555555'))))))&&&&&&v U   - + 7;())V33Xsx(M))))) *****%***GSXsx011M ^  F8888 ****AAAAMMMM5555CCCCaaaa????6666KQes.......r
