javascript - Node-forge decrypt aes-256-cbc shows ilegible characters

Question

Hi I have this code in node-forge. When I run this code, the decrypted data is "ilegible".

const keyHash = "d0f95d5e54a7aa25934a5d4915c9e2a06dadac20d16551693be1d21d4d8e8798"
//This keyHash really is in utf8: Nootric2703202 hash(sha256)

const encryptedB64 = "U2FsdGVkX1++7PN6CsF5Bi38t0N3EjXpH5oGpaIZXUwk4T8QCwcATjvA4b/8VaxD8nf/MZhKPnWb1L8raLR4lw==";

var encrypted = Buffer.from(encryptedB64, 'base64');

var key = Buffer.from(keyHash, 'hex');
var res = forgeDecrypt();



function forgeDecrypt() {
    const encoding = 'utf8';
    key = key.toString(encoding);
    initVal = encrypted.toString(encoding).substring(0, 16);
    encrypted = encrypted.toString(encoding).substring(16);
    var decipher = forge.cipher.createDecipher('AES-CBC', key);
    decipher.start({ iv: initVal });
    decipher.update(forge.util.createBuffer(encrypted));
    var result = decipher.finish();
    result = decipher.output.getBytes();
    return result;
 }

The real decrypted value must be like this:
