Creating JWTs #
You can use any package to implement the signCpf function, it should return an JWT token containing the user's CPF as chicoToken and your customer id as client.
Similar to eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJjaGljb1Rva2VuIjoiPENQRj4iLCJjbGllbnQiOiJkZW1vIn0.AZ8bbjN8yDLd1Fv283FxkXACSL6IbkCZilGG6726qz4
We recommend using dart_jsonwebtoken for the simplicity of it:
final jwt = JWT(
// Payload
{
'cpf': "000.111.222-33",
'client': "decom"
},
);

// Sign it (default with HS256 algorithm)
token = jwt.sign(SecretKey('secret passphrase'));

print('Signed token: $token\n');
