                                                         java.security.GeneralSecurityException

Sets the server's KeyPairProvider with the loaded identities - if any

Type Parameters:

S - The generic server type

Parameters:

server - The SshServer to configure

props - The Properties holding the server's configuration - ignored if null/empty

supportedOnly - If true then ignore identities that are not supported internally

Returns:

The updated server

Throws:

java.io.IOException - If failed to access the file system

java.security.GeneralSecurityException - If failed to load the keys

                                                  java.security.GeneralSecurityException

Parameters:

props - The Properties holding the server's configuration - ignored if null/empty

supportedOnly - If true then ignore identities that are not supported internally

options - The LinkOptions to use when checking files existence

Returns:

A KeyPair for the identities - null if no identities available (e.g., after filtering unsupported ones)

Throws:

java.io.IOException - If failed to access the file system

java.security.GeneralSecurityException - If failed to load the keys
