QNAP now requires builds to be signed with an HSM.
This removes support for signing with a local keypair.
This adds support for signing with a Google Cloud hosted key.
The key should be an RSA key with protection level `HSM` and that uses PSS padding and a SHA256 digest.
The GCloud project, keyring and key name are passed in as command-line arguments.
The GCloud credentials and the PEM signing certificate are passed in as Base64-encoded command-line arguments.
Updates tailscale/corp#23528
Signed-off-by: Percy Wegmann <percy@tailscale.com>
This change allows for the release/dist/qnap package to be used
outside of the tailscale repo (notably, will be used from corp),
by using an embedded file system for build files which gets
temporarily written to a new folder during qnap build runs.
Without this change, when used from corp, the release/dist/qnap
folder will fail to be found within the corp repo, causing
various steps of the build to fail.
The file renames in this change are to combine the build files
into a /files folder, separated into /scripts and /Tailscale.
