When selecting an SSH key, you can choose between various options.

       
Key File(s)
 

This will accept OpenSSH compatible private key files or certs. If you have a Putty ppk file, you will need to use putty-keygen to convert it into OpenSSH format.

PKCS#11 Library
 

PKCS#11 is an interface mostly used with card readers or other hardware keys. You select a Windows DLL or macOS dylib/so file which allows the ZOC Terminal to access the hardware keys. For example, for the relatively popular Yubi-Key plugs, the corresponding file would be C:\Program Files\Yubico\Yubico PIV Tool\bin\libykcs11.dll.

Global SSH Keys
 

ZOC allows to define global authentication keys via its Tools menu or through the SSH options window. When you choose this option, ZOC will use all of the keys defined there and will offer them to the server for authentication.

Windows Certificate
 

If you have authentication keys in the Windows Certificate Store, this option lets you choose one. This also applies to hardware, e.g. CAC/PIV cards or usb hardware keys which map their keys to the Windows Certificate Store.
