    Kali AMD64 bit sha1 Checksum Mismatch

    Hey there, just wanted to let anybody who cares to know that I got a bad checksum while I was verifying the direct ISO for Kali Linux 64 bit v1.1.0a from the main site (https://www.kali.org/downloads/). First download, I checked it with fciv and got:

    E:\Images>ls
    kali-linux-1.1.0a-amd64.iso

    E:\Images>fciv kali-linux-1.1.0a-amd64.iso -sha1
    //
    // File Checksum Integrity Verifier version 2.05.
    //
    5804cdc0d11d44d4e2b16008f6716ba22438401f kali-linux-1.1.0a-amd64.iso
    This was in comparison to the sha1 in the official the directory that claimed it should be:

    2b8d2db20e2709c5e9e0f9f9bbd8606c9b9e729f kali-linux-1.1.0a-amd64.iso
    So, to double check, I grabbed the torrent instead and it downloaded much faster. I ran the checksum on the torrent and got this:

    E:\Images>ls
    kali-linux-1.1.0a-amd64.iso kali-linux-1.1.0a-amd64.txt.sha1sum
    kali-linux-1.1.0a-amd64.torrent

    E:\Images>fciv kali-linux-1.1.0a-amd64.iso -sha1
    //
    // File Checksum Integrity Verifier version 2.05.
    //
    2b8d2db20e2709c5e9e0f9f9bbd8606c9b9e729f kali-linux-1.1.0a-amd64.iso
    This matches the previously listed sha1 checksum and also the listed checksum in the file 'kali-linux-1.1.0a-amd64.txt.sha1sum'.


    If you have gotten "5804cdc0d11d44d4e2b16008f6716ba22438401f kali-linux-1.1.0a-amd64.iso", please chime in. If it was a one-time mistake during transfer, awesome. If it's a fake mirror, that'd suck mega *****. Good thing I checked myself before I wrecked myself though.

    But as always,
    Safe cracking everybody!

    I used gpg to check the sha1sum against the one provided in the downloads server. Returned `gpg: Signature made Fri 13 Mar 2015 10:41:29 AM EDT using RSA key ID 7D8D0BF6
    gpg: BAD signature from "Kali Linux Repository <devel@kali.org>"` I kinda thought I was just doing it wrong, but now I wonder if I also have a bad copy. How did you do the checksum?
