Subject: [PATCH v6 0/2] generic: test HCTR2 filename encryption
Date: Tue, 9 Aug 2022 11:40:35 -0700 [thread overview]
Message-ID: <20220809184037.636578-1-nhuck@google.com> (raw)
HCTR2 is a new wide-block encryption mode that can used for filename encryption
in fscrypt. This patchset adds a reference implementation of HCTR2 to the
fscrypt testing utility and adds tests for filename encryption with HCTR2.
More information on HCTR2 can be found here: "Length-preserving encryption with
HCTR2": https://ia.cr/2021/1441
The patchset introducing HCTR2 to the kernel can be found here:
https://lore.kernel.org/linux-crypto/20220520181501.2159644-1-nhuck@google.com/
Changes in v6:
* Remove unused variable
* Rework cover letter
Changes in v5:
* Added links to relevant references for POLYVAL and HCTR2
* Removed POLYVAL partial block handling
* Referenced HCTR2 commit in test
Changes in v4:
* Add helper functions for HCTR2 hashing
* Fix accumulator alignment bug
* Small style fixes
Changes in v3:
* Consolidate tests into one file
Changes in v2:
* Use POLYVAL multiplication directly instead of using GHASH trick
* Split reference implementation and tests into two patches
* Remove v1 policy tests
* Various small style fixes
