Method Detail

getConfiguration

protected SshConfiguration getConfiguration()

getKeysForHost

public final SshHostKey[] getKeysForHost(java.lang.String host,
                                         java.lang.String type)

Description copied from interface: SshHostKeyManager

Get all the keys that are valid for the specified host and key type. The implementation may also use DNS to attempt to match against alternative hostnames (e.g. the IP address if the host is specified).

The returned list is guaranteed to be non-null, i.e. it will be empty if no matches are found.

Specified by:

getKeysForHost in interface SshHostKeyManager

Parameters:

host - host to match

type - type (one of SshConfiguration#PUBLIC_KEY_SSHDSS or SshConfiguration.PUBLIC_KEY_SSHRSA.

Returns:

keys

doGetKeysForHost

protected SshHostKey[] doGetKeysForHost(java.lang.String host,
                                        java.lang.String type)

Default simple implementation. Just calls SshHostKeyManager.getKeys() and matches the type and hostname. Providers may override if they have a more efficient method.

Parameters:

host - hostname

type - type

Returns:

host keys

checkHost

protected boolean checkHost(java.lang.String storedHostName,
                            java.lang.String hostToCheck)
