Hash: SHA512
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 | gpg --import
$ gpg --list-keys --with-fingerprint release-bookworm-images@turnkeylinux.org
pub rsa4096 2023-05-22 [SC] [expires: 2043-05-17]

sub rsa4096 2023-05-22 [S] [expires: 2043-05-17]
$ gpg --verify debian-12-turnkey-leantime_18.1-1_amd64.tar.gz.hash
gpg: Signature made using RSA key ID 26147592087C0EDE42143B637761DEBABBCFBA7C
gpg: Good signature from "0"
2. Recalculate the image hash and make sure it matches your choice of hash below.
$ sha256sum debian-12-turnkey-leantime_18.1-1_amd64.tar.gz

Note, you can compare hashes automatically::
$ sha256sum -c debian-12-turnkey-leantime_18.1-1_amd64.tar.gz.hash
debian-12-turnkey-leantime_18.1-1_amd64.tar.gz: OK
$ sha512sum -c debian-12-turnkey-leantime_18.1-1_amd64.tar.gz.hash
debian-12-turnkey-leantime_18.1-1_amd64.tar.gz: OK
Final note, when checking SHAs automatically, please ignore warning noting that some lines are improperly formatted.
