## Common API

kcapi_set_verbosity — set the verbosity level of the library
kcapi_versionstring — obtain version string of kcapi library
kcapi_version — return machine-usable version number of kcapi library
kcapi_pad_iv — realign the IV as necessary for cipher
kcapi_memset_secure — `memset` implementation that will not be optimized away by the compiler
kcapi_handle_reinit — re-initialize a new kernel interface
kcapi_set_maxsplicesize — Set maximum buffer size for splice
kcapi_get_maxsplicesize — Get maximum buffer size for splice

The following API calls are common to all cipher types.
