I got wrong signed hashes every time with the function web3.personal.sign.
With the following minimum PoC code, the generated result is wrong.
Of course, this code works perfectly with other environments like MetaMask and the Android version of Trust.
<html>
<head>
<script>
const sign = ()=>{
const message = 'Hello world!';
const signer = web3.eth.accounts[0];
web3.personal.sign(message, signer, (err, signature) => {
if (!err){
document.querySelector(".signer").innerText = signer;
document.querySelector(".message").innerText = message;
document.querySelector(".signature").innerText = signature;
}
});
}
</script>
</head>
<body onload="sign()">
<div>Signer: <span class="signer"></span></div>
<div>Message: <span class="message"></span></div>
<div>Signature: <span class="signature"></span></div>
</body>
</html>
The code above can be tested on the following URL.
It makes me confused that the service like OpenSea using this API works fine with Trust.
Is there another way to make a message personal-signed?

I found that the first parameter of web3.personal.sign is needed to be converted to hex manually with the method like web3.fromUtf8 or web3.utils.utf8ToHex.
I can get the correct result with iOS version of Trust.
The original code working with MetaMask and Android version of Trust mislead me.
