Subject: [U-Boot-Users] SHA1 Hash calculation
Date: Wed, 23 Nov 2005 08:32:32 +0100 (MET)	[thread overview]
Message-ID: <19732218.1132731152180.JavaMail.root@eni-cpps05.sth.basefarm.net> (raw)

Hi!

I am wondering whether it would be worth to implement a SHA1 hash 
calculation over given memory address range. In this way one could 
assure for example that the binary image version is correct or that 
binary image is intact.

For those who are not familiar waith SHA1 (or 
other hash algorithms), the SHA1 algorithm computes a 160 bit 
"fingerprint" of given byte stream. The algorithm is designed so that 
collisions between any given byte stream is "unlikely" as it is very 
unlikely that two persons have identical fingerprints or dna.

Any comments?
