java.lang.Object
  extended by org.apache.ftpserver.ssl.impl.AliasKeyManager
All Implemented Interfaces:
KeyManager, X509KeyManager

public final class AliasKeyManager
extends Object
implements X509KeyManager

Internal class, do not use directly. X509KeyManager which allows selection of a specific keypair and certificate chain (identified by their keystore alias name) to be used by the server to authenticate itself to SSL clients. This class is only used on Java 1.4 systems, on Java 1.5 and newer the @see ExtendedAliasKeyManager is used instead Based of org.apache.tomcat.util.net.jsse.JSSEKeyManager.

Method Detail

chooseClientAlias

public String chooseClientAlias(String[] keyType,
                                Principal[] issuers,
                                Socket socket)
Choose an alias to authenticate the client side of a secure socket, given the public key type and the list of certificate issuer authorities recognized by the peer (if any).

Specified by:
chooseClientAlias in interface X509KeyManager
Parameters:
keyType - The key algorithm type name(s), ordered with the most-preferred key type first
issuers - The list of acceptable CA issuer subject names, or null if it does not matter which issuers are used
socket - The socket to be used for this connection. This parameter can be null, in which case this method will return the most generic alias to use
Returns:
The alias name for the desired key, or null if there are no matches

chooseServerAlias

public String chooseServerAlias(String keyType,
                                Principal[] issuers,
                                Socket socket)
Returns this key manager's server key alias that was provided in the constructor.

Specified by:
chooseServerAlias in interface X509KeyManager
Parameters:
keyType - The key algorithm type name
issuers - The list of acceptable CA issuer subject names, or null if it does not matter which issuers are used (ignored)
socket - The socket to be used for this connection. This parameter can be null, in which case this method will return the most generic alias to use (ignored)
Returns:
Alias name for the desired key

getCertificateChain

public X509Certificate[] getCertificateChain(String alias)
Returns the certificate chain associated with the given alias.

Specified by:
getCertificateChain in interface X509KeyManager
Parameters:
alias - The alias name
Returns:
Certificate chain (ordered with the user's certificate first and the root certificate authority last), or null if the alias can't be found

getClientAliases

public String[] getClientAliases(String keyType,
                                 Principal[] issuers)
Get the matching aliases for authenticating the client side of a secure socket, given the public key type and the list of certificate issuer authorities recognized by the peer (if any).

Specified by:
getClientAliases in interface X509KeyManager
Parameters:
keyType - The key algorithm type name
issuers - The list of acceptable CA issuer subject names, or null if it does not matter which issuers are used
Returns:
Array of the matching alias names, or null if there were no matches

getServerAliases

public String[] getServerAliases(String keyType,
                                 Principal[] issuers)
