zx_status_t Init (digest::Algorithm digest, const Secret & ikm, const Bytes & salt, uint16_t flags)Initializes the HKDF algorithms indicated by |digest| with the input key material in |ikm|
and the given |salt|. Callers must omit |flags| unless the security implications are clearly
understood.

zx_status_t Derive (const char * label, size_t len, Bytes * out)Fill |out| with |len| bytes of output key material. The key material will depend on the
|ikm| and |salt| given in |Init|, as well as the |label| provided here. |out_key| will be
the same if and only if all of those parameters are unchanged.
