```
public interface HostKeyVerifier
```
Host key verification interface.

Method Summary

Modifier and Type	Method	Description
`java.util.List<java.lang.String>`	`findExistingAlgorithms(java.lang.String hostname, int port)`	It is necessary to connect with the type of algorithm that matches an existing know_host entry.
`boolean`	`verify(java.lang.String hostname, int port, java.security.PublicKey key)`	This callback is invoked when the server's host key needs to be verified.

- Method Detail
  - verify
```
boolean verify(java.lang.String hostname,
               int port,
               java.security.PublicKey key)
```
    This callback is invoked when the server's host key needs to be verified. The return value indicates to the caller whether the SSH connection should proceed.
    Note: host key verification is the basis for security in SSH, therefore exercise due caution in implementing!
    
    Parameters:
    
    hostname - remote hostname
    
    port - remote port
    
    key - host key of server
    
    Returns:
    
    true if key is acceptable, false otherwise
  - findExistingAlgorithms
```
java.util.List<java.lang.String> findExistingAlgorithms(java.lang.String hostname,
                                                        int port)
```
    It is necessary to connect with the type of algorithm that matches an existing know_host entry. This will allow a match when we later verify with the negotiated key HostKeyVerifier.verify
    
    Parameters:
    
    hostname - remote hostname
    
    port - remote port
    
    Returns:
    
    existing key types or empty list if no keys known for hostname
