I was downloading Kali Linux (via direct download) and noticed that the SHA1 checksum during download was different to the official values provided. However, after the download was completed, the checksum changed to that of the official value. Can anyone please provide some information regarding why it may have changed on this one occasion?
SHA1 during download: da39a3ee5e6b4b0d3255bfef95601890afd80709
SHA1 after download: 25cc6d53a8bd8886fcb468eb4fbb4cdfac895c65
Ordinarily, I would have thought that this is simply due to the download not being complete, however, in the past I have performed this same check when downloading Kali Linux and the checksum has been the same on all occasions.
I have searched for an answer, but could not find anything conclusive. I am now going to re-download via a torrent to see if the same occurs.
