May I know is there any s/w or solution that is able to auto discovery private key and public key in a connected environment/area?

For example like,

I have 3 Servers and 10 Clients. Then I need to know which Client's public key is located at which server.
And which server have an unknown public key.

Help!!!

Other wise,the best i can think of is this:

Hi,

Thanks for your answer.

But actually public key and wireless key are different.

Public key is something like bypass the password authentication for client to access server such as ssh, sftp, or scp.

what service/application?

for example, if you use ssh to connect on linux, you wouldn't know which machine because ssh is per user, and you can find all users' public key in /home/user-name/.ssh

also, auto discover for private key just does not make any sense. who want to use encryption where everybody can decrypt it?
