Subject: [PATCH] sha2-256 truncation
Date: Fri, 09 Jan 2004 09:50:58 +0100 [thread overview]
Message-ID: <3FFE6B72.9030808@logix.cz> (raw)
[-- Attachment #1: Type: text/plain, Size: 505 bytes --]
Hi,
the attached trivial patch corrects the truncation size of computed
hashes that are used in IPsec ESP/AH packets for SHA2-256. All other
hash algorithms use 96 bits as well as does SuperFreeS/WAN and FreeBSD
also for SHA2-256. Only the native Linux sha2-256 used 128 bits what led
to incompatibility with other IPsec implementations.
Please apply, thanks!
Michal Ludvig
