Hello,
Can I know the status of this patch, and the possible impact on any existing applications because the partial hash is switched from OpenSSL to intel-ipsec-mb which is not under FIPS certification?
Thanks!

Subject: Re: [External] : [PATCH] crypto/qat: use intel-ipsec-mb for partial hash
Hi Fan,
Does it mean the intel-ipsec-mb would be prerequisite of applying QAT offloading for security application? It this is the case, as I know, the intel-ipsec-mb has no FIPS certification yet. Thus I am thinking
this would impact existing QAT based security application, right?
Best Regards,
Changchun Zhang

Subject: [External] : [PATCH] crypto/qat: use intel-ipsec-mb for partial hash
Since openssl 3.0 now deprecates the low level API QAT required to
perform partial hash operation when creating the session. This
patch is to transfer such dependency from openssl to intel-ipsec-mb.
