Re: [Clip] Re: MD5 checksum clip
- I guess it could be likened to a fingerprint.
MD5's can be used to determine that the file or iso you downloaded is a
bit-for-bit copy of the remote file or iso.</quote>
On Linux, (man md5sum) I use the command:
to verify a Linux .iso file that I downloaded. At www or ftp site where the
.iso file is stored also exists a text file containing md5sums for any .iso
files that are on that site.
That command up there returns the "fingerprint" of the file that's on my
hard drive. Such fingerprint must match the fingerprint that's in the
mentioned text file at the remote site where I downloaded the .iso file
from. A match tells me that my file is ok that it's an exact copy of the
remote file that I downloaded.
Out of over hundreds of downloads, it has only been once that it did not
match which tell me my download is corrupt (I deleted it and re downloaded
and then the two fingerprints matches)
In that way, verifies authenticity versus a piece of the file is

Still doesn't match the signature at your page though. Could you have used
^$GetMD5Text()$ when you produced that, too?
>>Could you have used ^$GetMD5Text()$ when you produced that, too?<<I bet Lotta is right (as usual). Using the NoteTab clip for Get md5 of
FILE in the Utilities Library, I get the following result on both
verions of the file I downloaded from your site:
MD5 signature of "E:\Software Downloads\ColorPalates.zip":
