Constructor Detail

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 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).

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 - Ignored

issuers - Ignored

socket - 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

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

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

chooseEngineClientAlias

public String chooseEngineClientAlias(String[] keyType,
                                      Principal[] issuers,
