Philippe Reynes <philippe.reynes@softathome.com> says:

This serie adds the support of sha256_hmac and sha256_hkdf.
A first version was sent several months ago just before the
integration of mbedtls. This new version is based on mbedtls.

The first patch of this serie add the support of hkdf
using mbedtls.
