HKDF computes HKDF (as specified by RFC 5869) of initial keying
material |secret| with |salt| and |info| using |digest|, and
outputs |out_len| bytes to |out_key|. It returns one on success and
zero on error.
HKDF is an Extract-and-Expand algorithm. It does not do any key
stretching, and as such, is not suited to be used alone to generate
a key from a password.
