Hi @WagdeoA 

There’s no problem in your configuration.

It works on my side. But one possible issue could be the length of tag (secondaryInputLength).

This can be found in function Crypto_Ipw_HmacVerify:

If redirection is disabled, it’s necessary to provide the length of tag in bits, not in bytes. Isn’t this the problem?
