it seems like on some versions of 4D (for Mac),
an invisible character is appended at the end for alignment.

that would screw up the barcode data.

But we ended up using hmBarcode because the free fonts didn't work 
with new scanners that the client got.

Re: HMAC SHA256 in native 4D code

[Two Way Communications via 4D_Tech]

Hi Bruno,

Thank you very much.
This does in fact generate the correct JWT.

I did check where the differences are,  comparing to my code:
Apparently, when using the php function ‘hash_hmac’, or when using Openssl 
through LEP, I get another signature than the one I get from your component.

I am not sure why that is, since the input is exactly the same. 

Anyway, a big thanks. I spent hours trying to generate the JWT with the php / 
openssl and couldn’t figure it out.


Can anyone explain why the results are different? Because I would really like 
to know.

Hi Ruby,

I sent you a component which does HMAC 256 and JWT object signing.
It is all native.

Lets us know if it works.
