### MAC gap analysis ### MAC gap analysis
[TODO] The legacy API does not have a unified interface for MAC, only separate interfaces for HMAC and CMAC. As a consequence, applications need ad hoc code to support both HMAC and CMAC anyway. With respect to MAC mechanism identification, there is no gap to fill.
Within the scope of HMAC, applications need to convert between hash mechanism identifications; this is part of the more general [hash analysis](#hash-gap-analysis). Within the scope of CMAC, applications need to convert between block cipher identifications; this is part of the more general [cipher and AEAD analysis](#cipher-and-aead-gap-analysis).
MAC do not have any nontrivial format for keys or outputs, so there is no need for any conversion functions.
