40 An application may need to securely establish the context within which this
43 the context. The context value is left to the application but must be the same
47 B<out>. The application specific context should be supplied in the location
48 pointed to by B<context> and should be B<contextlen> bytes long. Provision of
49 a context is optional. If the context should be omitted entirely then
51 B<use_context> is 0 then the values of B<context> and B<contextlen> are ignored.
52 Note that in TLSv1.2 and below a zero length context is treated differently from
53 no context at all, and will result in different keying material being returned.
54 In TLSv1.3 a zero length context is that same as no context at all and will
