Detailed Description

These operations make, validate, encode and decode a Receiver Secret Key (RSK).

An RSK is required to derive an SSV (see wc_DeriveSakkeSSV()).

On the KMS, make an RSK (wc_MakeSakkeRsk()) from the client's ID.

On the client, validate the RSK (wc_ValidateSakkeRsk()) with the ID.

Encode the RSK (wc_EncodeSakkeRsk()) to pass to client or for storage.

Decode the RSK (wc_DecodeSakkeRsk()) on the client when needed.

Import the RSK (wc_ImportSakkeRsk()) on the client when needed.

Set the RSK and, optionally, a pre-computation table (wc_SetSakkeRsk()) on the client when needed.
