This patchset is not intended to be accepted yet. It is reliant on HCTR2 support in the kernel which has not yet been accepted. See the HCTR2 patchset here: https://lore.kernel.org/all/20220504001823.2483834-1-nhuck@xxxxxxxxxx/ 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 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 Nathan Huckleberry (2): fscrypt-crypt-util: add HCTR2 reference implementation generic: add tests for fscrypt policies with HCTR2 common/encrypt | 2 + src/fscrypt-crypt-util.c | 338 ++++++++++++++++++++++++++++++++------- tests/generic/900 | 24 +++ tests/generic/900.out | 6 + tests/generic/901 | 26 +++ tests/generic/901.out | 6 + tests/generic/902 | 26 +++ tests/generic/902.out | 6 + 8 files changed, 377 insertions(+), 57 deletions(-) create mode 100755 tests/generic/900 create mode 100644 tests/generic/900.out create mode 100755 tests/generic/901 create mode 100644 tests/generic/901.out create mode 100755 tests/generic/902 create mode 100644 tests/generic/902.out -- 2.36.0.512.ge40c2bad7a-goog
