Subject: crypto ahash error handling
Date: Mon, 08 Nov 2010 10:48:30 +0200	[thread overview]
Message-ID: <4CD7B95E.9040501@nokia.com> (raw)

Hello,

When using crypto ahash API, is it necessary/mandatory to call
crypto_ahash_final() if crypto_ahash_update() returns error...

Basically it might happen after several calls while calculating hash if
HW error happens.
It is not possible to continue hash calculation. it is necessary to
reset HW and start whole hash again..

Any comments?

Thanks,
Dmitry
