Detailed Description

Key ordering of the key2.keys array.

This structure takes care of correct ordering when using unidirectional or bidirectional key material, and allows the same shared secret key file to be loaded in the same way by client and server by having one of the hosts use an reversed ordering.

◆ in_key

int key_direction_state::in_key

◆ need_keys

int key_direction_state::need_keys
