Subject: Exploiting SHA1's  "XOR weakness" allows for faster hash calculation
Date: Wed, 05 Dec 2012 10:19:43 +0100	[thread overview]
Message-ID: <k9n3jd$akg$1@ger.gmane.org> (raw)

Hi,

to say it in advance: I do not want to trigger any bogus security 
discussion here. Instead, I believe the findings from [1] allow for an 
up to 20% faster SHA1 calculation, if my brief reading of the 
presentation is correct. Any opinions on integration this optimization 
into Git?
