Constructor Details

JSSEKeyManager

public JSSEKeyManager(X509KeyManager mgr,
                      String serverKeyAlias)
Constructor.

Parameters:
mgr - The X509KeyManager used as a delegate
serverKeyAlias - The alias name of the server's keypair and supporting certificate chain

Method Details

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).

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.

Parameters:
keyType - The key algorithm type name (ignored)
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.

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).

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


getPrivateKey

public PrivateKey getPrivateKey(String alias)
Returns the key associated with the given alias.

Parameters:
alias - The alias name

Returns:
The requested key, or null if the alias can't be found


getServerAliases

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

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
