Define CKD_SHA256_KDF transformation to be used with CKM_ECDH1_DERIVE. Some HSM with FIPS restriction will refuse to derive keys with CKD_NULL. CKD_SHA256_KDF will do fine though. Unfortunately this is not implemented on softHSM (softhsm/SoftHSMv2#599) so I provide no test. This was tested fine against Thales DPOD. Signed-off-by: François Rigault <rigault.francois@gmail.com>
