From e1a6dc91ddb55ef77a705b62b6e62634631fd57d Mon Sep 17 00:00:00 2001 From: "Richard W.M. Jones" Date: Tue, 3 Jul 2018 09:03:03 +0100 Subject: crypto: Implement TLS Pre-Shared Keys (PSK). MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Pre-Shared Keys (PSK) is a simpler mechanism for enabling TLS connections than using certificates. It requires only a simple secret key: $ mkdir -m 0700 /tmp/keys $ psktool -u rjones -p /tmp/keys/keys.psk $ cat /tmp/keys/keys.psk rjones:d543770c15ad93d76443fb56f501a31969235f47e999720ae8d2336f6a13fcbc The key can be secretly shared between clients and servers. Clients must specify the directory containing the "keys.psk" file and a username (defaults to "qemu"). Servers must specify only the directory. Example NBD client: $ qemu-img info \ --object tls-creds-psk,id=tls0,dir=/tmp/keys,username=rjones,endpoint=client \ --image-opts \ file.driver=nbd,file.host=localhost,file.port=10809,file.tls-creds=tls0,file.export=/ Example NBD server using qemu-nbd: $ qemu-nbd -t -x / \ --object tls-creds-psk,id=tls0,endpoint=server,dir=/tmp/keys \ --tls-creds tls0 \ image.qcow2 Example NBD server using nbdkit: $ nbdkit -n -e / -fv \ --tls=on --tls-psk=/tmp/keys/keys.psk \ file file=disk.img Signed-off-by: Richard W.M.
