decode verify fail

[gith-u-b]

hi,

params:

{
    "message": "I'm verifying my DOT address",
    "address": "5HBwjWDWZTqRCv98pku9NwoSRo7euCowciut12tviPNAt7WK",
    "signature": "0xc02fd26ba216daa8cd285314a8059aa60744fd5cff1af606e14a9160c854a57c6b42abe0a986ae6b868703359c32c55069b819d23217f01ac513f8bc51482683"
}

use codes:

  server.post<{ Body: { message: string, signature: string, address: string } }>("/worker/dotSignatureVerify", async (request, reply) => {
    let {message, signature, address} = request.body

    await cryptoWaitReady();

    const isValid  = signatureVerify(stringToU8a(message), signature, address);

    return { isValid: isValid }
  });

is_valid is true, but use:

verify_result = SR25519.verify("5HBwjWDWZTqRCv98pku9NwoSRo7euCowciut12tviPNAt7WK", "I'm verifying my DOT address", "0xc02fd26ba216daa8cd285314a8059aa60744fd5cff1af606e14a9160c854a57c6b42abe0a
986ae6b868703359c32c55069b819d23217f01ac513f8bc51482683")

is false

use sign a message:

@xuxiaohu help🙏

[xuxiaohu]

can you try SR25519.verify(Address.encode("5HBwjWDWZTqRCv98pku9NwoSRo7euCowciut12tviPNAt7WK"), "I'm verifying my DOT address", "0xc02fd26ba216daa8cd285314a8059aa60744fd5cff1af606e14a9160c854a57c6b42abe0a
986ae6b868703359c32c55069b819d23217f01ac513f8bc51482683")?

Address.encode

forget it, run this and exit directly。。

The issue is w3f/schnorrkel#77
and maybe the polkajs do some extra sign.
the https://gist.github.com/EclesioMeloJunior/bb1a65e22aa2a4e27263206b42e34c43 is simple answer.
and you can verify it by SR25519.verify(address, "" + message + "", sign)

SR25519.verify(address, "" + message + "", sign)

I'm very sorry to bother you, the result is still false😢

SR25519.verify(address, "<Bytes>" + message + "</Bytes>", sign)
