RE: [GNUnet-developers] ripe-md160/HashCode160/CRC/MD5

Hello Christian,

>Read http://www.ovmj.org/GNUnet/download/ecrs.ps

I see a lot of strange characters in the document. Which viewer should I
open this file?

I have made a hash format. See the included file for the details.

Hash=Ripe-md160(file) + MD5(file) + Crc32(file) +
Filelength_reverse_order(file) + Crc32(Ripe-md160(file) + MD5(file) +
Crc32(file) + Filelength_reverse_order(file))

The hash:

1)      variable length because file length (hex notation) is variable.
2)      The file will be read 1 time only. The blocks (block size = 65 kB) of 
the
file will be read in a buffer sequentially.
3)      You can see in the second Crc32 if the format is a good format.
4)      It works on Redhat 9.0 and Microsoft Visual Studio (MVC).

The only problem I have is that big files in a Linux environment doesn’t
seem to open. This is not a problem in my Windows2000 professional
environment.

# ./fshhash /usr/local/fsh-20031123.tar.gz
