It isnt possible to sign binary data?

[honiahaka10]

Hi! I want to sign binary data in payload.
Payload is detached and headers are:
['b64' => false, 'crit' => ['b64']].

$jwsBuilder = new JWSBuilder([new PS256]);
$jwsBuilder = $jwsBuilder->create()->withPayload($binaryPayload, true);

This causes new InvalidArgumentException('The payload must be encoded in UTF-8');
When i get rid of that exception by manually deleting it signing and verifying just works fine.

rfc7797 should allow binary detached payload.
https://datatracker.ietf.org/doc/html/rfc7797#section-5.1
A detached payload can contain any octet sequence representable by the application.

Am I doing something wrong or should the UTF-8 check only be done with nondetached payloads?

Best Regards

Hi,

Thank you for reporting this issue. Indeed, UTF8 is only required for unencoded non-detached payload. This exception should not be thrown.
I will fix it ASAP.
