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.z#Message hash must be 32 bytes long.zsecp256k1_ecdsa_signature *z.The DER-encoded signature could not be parsed.) r newr secp256k1_ec_pubkey_parsectxr;rv MSG_HASH_SIZE#secp256k1_ecdsa_signature_parse_dersecp256k1_ecdsa_verify) signaturemessage public_keyhashercontextpubkey pubkey_parsedrwmsg_hashsig sig_parsedverifieds rverify_signatureres,WW) *F11'++vSVWaSbcM Ao"("4vg'H 8} %3o ''/ 0C88cVYZcVdeJ >o))'++sfMH|rNr6)r=r(r'r()rr7r'rA)rKrAr'r7)r=r(r'r7)rWr7rXrAr'zGenerator[bytes, None, None])rcr7r'r7)rir7r'r7)r'r7)rrr7r'r7)ror7r'r7) rr7rr7rr7rrrr r'bool)0 __future__rbase64rrhashlibrrosrrtypingr coincurve._libsecp256k1r r coincurve.contextr r collections.abcrcoincurve.typesrrnrurlr}rmrarbgetNULL DEFAULT_NONCEtuplerr/r>rCrLrOrRr\rdrjrprNrxrr!rrrs+"'% ,5)&v U   - +  ;;()V3XXsxx(M) *%*SXXsxx01M  F8 *AM5Ca?6KQes..$.27.AG.[b. .r
