There's system-titles which [[20.0.0|use]] SetProtocol. While there's game(s) which use SetProtocol, there's no known (?) games using Protocol3 (excluding GameShare which is system).

Protocol2 and Protocol4 appear to be identical to Protocol3 except for using [[SPL_services|Ounce]] keys (?)~~, with AES-128~~. It's unknown exactly which Protocol uses which [[SPL_services|Generation]], though presumably 2/4 is Generation 0x0/0x1? lcs (local-content-share) uses Generation 0x1, while Mario Kart World uses 0x0.

[S2] Protocol2 and Protocol4 appear to be identical to Protocol3 except for using [[SPL_services|Ounce]] keys (?). It's unknown exactly which Protocol uses which [[SPL_services|Generation]], though presumably 2/4 is Generation 0x0/0x1? lcs (local-content-share) uses Generation 0x1, while Mario Kart World uses 0x0.

[S2] Keys are generated by passing the SHA256 hash as the KeySource to the relevant [[SPL_services|spl:ldn]] command with the above Generation, with the full hash being passed to the Ounce cmds. Only the first 0x10-bytes of the output key is used, since AES-128 is used even with Ounce.

On NX, the Protocol [[#SetProtocol|permission-bitmask]] is always set to 0xA (1 and 3). On Ounce, all services have this set to 0x1E, except for one which has it set to 0xA (which is likely the one for S1-compat). 0x1E allows additional protocol values 2 and 4.
