Subject: [dpdk-users] AES "Digest-encrypted" crypto chain case.
Date: Mon, 9 Sep 2019 09:15:32 +0000
Message-ID: <8bbd488f54dc428ab9ec046639a633d0@de-mta1.commagility.com> (raw)

Hi All,
I am trying to test AES symmetric crypto case  "Digest-encrypted" by chaining Authentication operation followed by Ciphering.
Digest data pointer, Ciphering lengths etc., are configured such that ciphering operation includes the digest data (as mentioned in ‘rte_crypto_sym.h’ line:650-715).

With QAT PMD, I see the ‘raw’ digest data overwritten on the ciphered output as end result.

This issue is seen only with AES - ‘Digest-Encrypt’ chained operation. Not with Snow3G/ZUC chained operations.

Does anyone face this issue?

Regards,
Naveen
