Expand the supplied prk into several additional pseudorandom keys, which is the output of the HKDF.
int mbedtls_hkdf_extract(const mbedtls_md_info_t *md, const unsigned char *salt, size_t salt_len, const unsigned char *ikm, size_t ikm_len, unsigned char *prk)
Take the input keying material ikm and extract from it a fixed-length pseudorandom key prk.

This is the HMAC-based Extract-and-Expand Key Derivation Function (HKDF).
