Subject: [RFC v2.1 3/6] crypto: GnuPG based MPI lib - make files needed for ksign
Date: Tue, 13 Sep 2011 17:20:10 +0300 [thread overview]
Message-ID: <01cf591b5e8cf6cdfac854ceb6109b6a6179e823.1315921427.git.dmitry.kasatkin@intel.com> (raw)

In-Reply-To: <cover.1315921427.git.dmitry.kasatkin@intel.com>
Adds the multi-precision-integer maths library which was originally taken
from GnuPG and ported to the kernel by (among others) David Howells.
This version is taken from Fedora kernel 2.6.32-71.14.1.el6.
The difference is that checkpatch reported errors and warning has been fixed.
This library is used to implemenet RSA digital signature verification
used in IMA/EVM integrity protection subsystem.
