To ensure the image has not been corrupted in transmit or tampered with,
perform the following two steps to cryptographically verify image integrity:

1. Verify the authenticity of this file by checking that it is signed with our
   GPG release key:

    $ curl https://raw.githubusercontent.com/turnkeylinux/common/master/keys/tkl-buster-images.asc | gpg --import
    $ gpg --list-keys --with-fingerprint release-buster-images@turnkeylinux.org
      pub   rsa4096 2020-02-05 [SC] [expires: 2040-01-31]
            A8B2 EF42 8781 9B03 D351  6CCA 7623 1C20 425E 9772
      uid           [ unknown] TurnKey GNU/Linux Buster Images (GPG signing key for TurnKey Linux Buster Images) <release-buster-images@turnkeylinux.org>
      sub   rsa4096 2020-02-05 [S] [expires: 2040-01-31]
      
    $ gpg --verify turnkey-silverstripe-16.1-buster-amd64.iso.hash
      gpg: Signature made using RSA key ID A8B2EF4287819B03D3516CCA76231C20425E9772
      gpg: Good signature from "0"

2. Recalculate the image hash and make sure it matches your choice of hash below.

    $ sha256sum turnkey-silverstripe-16.1-buster-amd64.iso
      5b9ccc6662608c25401c5615a8998c5a85ae4452b7887fab425cbad5e8490d9c  turnkey-silverstripe-16.1-buster-amd64.iso

    $ sha512sum turnkey-silverstripe-16.1-buster-amd64.iso
      3453d8de15c70d4f675a45e269db5c3f3c09761d764bbb735ee4ee35ab4bd330cc2856215284b45e9bd69b2d9c5b854e92ae87305dc64c12b4b98e04c36962a0  turnkey-silverstripe-16.1-buster-amd64.iso

    $ sha256sum -c turnkey-silverstripe-16.1-buster-amd64.iso.hash
      turnkey-silverstripe-16.1-buster-amd64.iso: OK

    $ sha512sum -c turnkey-silverstripe-16.1-buster-amd64.iso.hash
      turnkey-silverstripe-16.1-buster-amd64.iso: OK
