Class KeyManagerUtils

java.lang.Object

org.apache.commons.net.util.KeyManagerUtils

public final class KeyManagerUtils
extends Object

General KeyManager utilities

How to use with a client certificate:

 KeyManager km = KeyManagerUtils.createClientKeyManager("JKS",
     "/path/to/privatekeystore.jks","storepassword",
     "privatekeyalias", "keypassword");
 FTPSClient cl = new FTPSClient();
 cl.setKeyManager(km);
 cl.connect(...);
 

If using the default store type and the key password is the same as the store password, these parameters can be omitted.

If the desired key is the first or only key in the keystore, the keyAlias parameter can be omitted, in which case the code becomes:

 KeyManager km = KeyManagerUtils.createClientKeyManager(
     "/path/to/privatekeystore.jks","storepassword");
 FTPSClient cl = new FTPSClient();
 cl.setKeyManager(km);
 cl.connect(...);

public static KeyManager createClientKeyManager(File storePath,
                                                String storePass)
                                         throws IOException,
                                                GeneralSecurityException

Create a client key manager which returns a particular key. Does not handle server keys. Uses the default store type and assumes the key password is the same as the store password. The key alias is found by searching the keystore for the first private key entry

Parameters:

storePath - the path to the keyStore

storePass - the keyStore password

Returns:

the customized KeyManager

Throws:

IOException - if there is a problem creating the keystore

GeneralSecurityException - if there is a problem creating the keystore
