systemd-id128: a new tool to print machine/boot/invocation/app-specific ids
The raison d'etre for this program is printing machine-app-specific IDs. We
provide a library function for that, but not a convenient API. We can hardly
ask people to quickly hack their own C programs or call libsystemd through CFFI
in python or another scripting language if they just want to print an ID.
Verb 'new' was already available as 'journalctl --new-id128', but this makes
it more discoverable.
v2:
- rename binary to systemd-id128
- make --app-specific= into a switch that applies to boot-id and machine-id

This way, the ID used by the application remains stable on a given machine, but cannot be easily correlated with IDs used in other applications on the same - machine. The application-specific ID should be generated via a tool like <command>journalctl --new-id128</command>, + machine. The application-specific ID should be generated via a tool like <command>systemd-id128 new</command>, and may be compiled into the application. This function will return the same application-specific ID for each combination of machine ID and application ID. Internally, this function calculates HMAC-SHA256 of the application ID, keyed by the machine ID.</para> @@ -145,6 +145,7 @@ <para> <citerefentry><refentrytitle>systemd</refentrytitle><manvolnum>1</manvolnum></citerefentry>, + <citerefentry><refentrytitle>systemd-id128</refentrytitle><manvolnum>1</manvolnum></citerefentry>, <citerefentry><refentrytitle>sd-id128</refentrytitle><manvolnum>3</manvolnum></citerefentry>, <citerefentry><refentrytitle>machine-id</refentrytitle><manvolnum>5</manvolnum></citerefentry>, <citerefentry><refentrytitle>systemd.exec</refentrytitle><manvolnum>5</manvolnum></citerefentry>, |
