Jwt.io can't validate JWT with valid key

Can’t validate the JWT using the key.


The key for the JWT above is ‘minha-esponja’, but it is not working.

Follow my PHP code:


$key = ‘minha-esponja’;

$header = [
‘alg’ => ‘HS256’,
‘typ’ => ‘JWT’

$header = json_encode($header);

$header = base64_encode($header);

$payload = [
‘iss’ => ‘localhost’,
‘name’ => ‘Diogo’,
‘email’ => ‘diogo.fragabemfica@gmail.com’

$payload = json_encode($payload);

$payload = base64_encode($payload);

$signature = hash_hmac(‘sha256’,"$header.$payload", $key,true);

$signature = base64_encode($signature);

echo “$header.$payload.$signature”;

echo ‘


$token = “$header.$payload.$signature”;

echo $token;
