ahash and crc32c

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi,

I'm working on an ahash driver that supports CRC32C.
I saw that all existing CRC32C implementations (except blackfin) are
implementing shash interface, but ahash seems to be the correct choice
in our case.
On the other hand I saw that CRC32C test in testmgr.c tries to create
shash tfm for CRC32C and assumes that the CRC context is saved in first
4 bytes of the shash context.

When I implement CRC32C algorithm this part of the test fails.

How should I treat this failure? What is the reason for the requirement
that is tested in this scenario?

Thank you.
Zeev.
