[dpdk-users] AES "Digest-encrypted" crypto chain case.

[Naveen Kumar]

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
