NAME

       kcapi_kpp_ssgen - generate a shared secret

SYNOPSIS

       int32_t kcapi_kpp_ssgen(struct kcapi_handle * handle, const uint8_t * pubkey,
                               uint32_t pubkeylen, uint8_t * ss, uint32_t sslen, int access);

ARGUMENTS

       handle
           [in] cipher handle

       pubkey
           [in] public key of peer that shall be used to generate the shared secret with

       pubkeylen
           [in] length of the public key buffer

       ss
           [out] generated shared secret

       sslen
           [in] length of key buffer

       access
           [in] kernel access type (KCAPI_ACCESS_HEURISTIC - use internal heuristic for fastest
           kernel access; KCAPI_ACCESS_VMSPLICE - use vmsplice access; KCAPI_ACCESS_SENDMSG -
           sendmsg access)

DESCRIPTION

       return number of bytes returned by the shared secret generation operation upon success; a
