--------------
NIST SP800-56Cr2 One-Step KDM
-----------------------------

NIST [SP800-56Cr2]_ defines a one-step key derivation method based on a hash
function, HMAC, or KMAC. All three of these options are supported. The
implementation can be found in
:srcref:`src/lib/kdf/sp800_56a/sp800_56c_one_step.cpp`.

NIST SP800-56Cr2 Two-Step KDM
-----------------------------

NIST [SP800-56C]_ defines a key derivation using extraction-then-expansion.
The implementation can be found in
:srcref:`src/lib/kdf/sp800_56c/sp800_56c_two_step.cpp`. The implementation fixes the
context value for the expansion step to the empty string.
