Intel has rolled out a new quarterly update to QATlib, its QuickAssist Technology library for Linux systems to enjoy hardware acceleration of various crypto and compression algorithms on QAT Gen 4 hardware.

In addition to the many algorithms and features already supported for security / authentication / compression offloading to QAT accelerators, QATlib 23.11 rolls out a couple more features. The QATlib 23.11 highlights include:
- Support DC NS (NoSession) APIs
- Support Symmetric Crypto SM3 & SM4
- Support Asymmetric Crypto SM2
- Support DC CompressBound APIs
- Bug Fixes

QATlib 23.11 can be downloaded via GitHub .


Meanwhile the Intel QAT kernel driver support continues improving as well. With Linux 6.7 there is more efficient use of Gen4 QAT hardware via chained compression "DC" operations. With a single firmware request the chained operations allow for hashing and then compressing the data in one-go.
