The <Manage Authentication Keys> dialog shows a list of all available public/private key pairs available on the server to which the RAT is connected. The <Fingerprint> column shows the SHA256 hash value of the public key of every public/private key pair in the list. If desired the full public keys can be shown instead. Thereto the <Show full public keys> checkbox must be ticked. Upon ticking the checkbox, the Column <Fingerprint> will be renamed to <Public Key> and will show the public key of every public/private key pair in the list.
