Interface X509KeyManager

All Superinterfaces:: KeyManager

public interface X509KeyManager
extends KeyManager

Instances of this interface manage which X509 certificate-based key pairs are used to authenticate the local side of a secure socket.

During secure socket negotiations, implentations call methods in this interface to:

determine the set of aliases that are available for negotiations based on the criteria presented,
select the best alias based on the criteria presented, and
obtain the corresponding key material for given aliases.

Since:: 1.4

Method Summary

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).

String chooseServerAlias(String keyType, Principal[] issuers, Socket socket)
          Choose an alias to authenticate 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).

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

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).

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

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).

Method Detail

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:: an array of the matching alias names, or null if there were no matches.

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.

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:: an array of the matching alias names, or null if there were no matches.

chooseServerAlias

public String chooseServerAlias(String keyType,
                                Principal[] issuers,
                                Socket socket)

Choose an alias to authenticate 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.; 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.

getCertificateChain

public X509Certificate[] getCertificateChain(String alias)

Returns the certificate chain associated with the given alias.

Parameters:: alias - the alias name
Returns:: the certificate chain (ordered with the user's certificate first and the root certificate authority last), or null if the alias can't be found.

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.
