Multiple pubkeys/pkeys

[kdh4318]

Hello

I've tested the case where the server and client own multiple pkeys and pubkeys, and I've come to the conclusion of the following.
Could you confirm if it's correct?

When the server owns multiple pubkeys, only the pubkey with the fastest name recognizes it as the server's authentication key.
That is, if the server owns A, B, C, and D, even if the client owns B, C, and D, authentication fails because A is not present.

The server send his keyname 20250325_Server_ClientAuth.pubkey
And the client use the key that start with 20250325

The client can have multiple keys, but the server only has one key

Hello,

I don't understand the saying that the server only has one key. For the pubkey and pkey generated to work properly, the pubkey must exist in the folder where winvnc.exe is located, and the pkey must exist in the folder where vncviewer.exe is located.

This means that if there are multiple keys in the folder, vncviewer can have multiple pkeys and winvnc can have multiple pubkeys.

I tested this part. When AAA_Server_ClientAuth.pubkey, BBB_Server_ClientAuth.pubkey, and CCC_Server_ClientAuth.pubkey were located in the winnc.exe folder, the connection failed even if BBB_Viewer_ClientAuth.pkey and CCC_Viewer_ClientAuth.pkey were located in the vncviewer folder. The connection was successful only when AAA_Viewer_ClientAuth.pkey was located.

Am I wrong about how to use the Client Authentication Key?

server A 123_server_key A
server B 456_server_key B

viewer 123_viewer_key A and 456_viewer_key B

viewer can connect to server A and B
