Detailed Description

These operations transfer a Shared Secret Value (SSV) from one client to another. The SSV may be randomly generated.

Calculate the size of the authentication data (wc_GetSakkeAuthSize()) to determine where the SSV starts in a buffer.

Make the intermediate point I (wc_MakeSakkePointI()) to speed making an encapsulated and deriving SSV.

Get intermediate point I (wc_GetSakkePointI()) for storage.

Set intermediate point I (wc_SetSakkePointI()) from storage.

Generate a pre-computation table for intermediate point I (wc_GenerateSakkePointITable()) to further enhance performance. Store as necessary.

Set the pre-computation table for intermediate point I (wc_SetSakkePointITable()) to further enhance performance.

Clear the pre-computation table for intermediate point I (wc_ClearSakkePointITable()) to remove reference to external table pointer.

Make an encapsulated SSV (wc_MakeSakkeEncapsulatedSSV()) to share with another client. Data in SSV is modified.

Generate a random SSV (wc_GenerateSakkeSSV()) for key exchange.

Derive the SSV, (wc_DeriveSakkeSSV()) on the recipient from the encapsulated SSV.
