X509KeyManager

public interface X509KeyManager
implements KeyManager

javax.net.ssl.X509KeyManager

Known indirect subclasses

X509ExtendedKeyManager Abstract class that provides for extension of the X509KeyManager interface.

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.

Note: the X509ExtendedKeyManager should be used in favor of this class.

Summary

Public methods
`abstract 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).

`abstract X509Certificate[]`	`getCertificateChain(String alias)` Returns the certificate chain associated with the given alias.
`abstract 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).
`abstract PrivateKey`	`getPrivateKey(String alias)` Returns the key associated with the given alias.
`abstract 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).

Public methods

chooseClientAlias

Added in API level 1

public abstract 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`	`String`: the key algorithm type name(s), ordered with the most-preferred key type first.
`issuers`	`Principal`: the list of acceptable CA issuer subject names or null if it does not matter which issuers are used.
`socket`	`Socket`: the socket to be used for this connection. This parameter can be null, which indicates that implementations are free to select an alias applicable to any socket.

Returns
`String`	the alias name for the desired key, or null if there are no matches.

chooseServerAlias

Added in API level 1

public abstract 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`	`String`: the key algorithm type name.
`issuers`	`Principal`: the list of acceptable CA issuer subject names or null if it does not matter which issuers are used.
`socket`	`Socket`: the socket to be used for this connection. This parameter can be null, which indicates that implementations are free to select an alias applicable to any socket.

Returns
`String`	the alias name for the desired key, or null if there are no matches.

getCertificateChain

Added in API level 1

public abstract X509Certificate[] getCertificateChain (String alias)

Returns the certificate chain associated with the given alias.

Parameters
`alias`	`String`: the alias name

Returns
`X509Certificate[]`	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.

getClientAliases

Added in API level 1

public abstract 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`	`String`: the key algorithm type name
`issuers`	`Principal`: the list of acceptable CA issuer subject names, or null if it does not matter which issuers are used.

Returns
`String[]`	an array of the matching alias names, or null if there were no matches.

getPrivateKey

Added in API level 1

public abstract PrivateKey getPrivateKey (String alias)

Returns the key associated with the given alias.

Parameters
`alias`	`String`: the alias name

Returns
`PrivateKey`	the requested key, or null if the alias can't be found.

getServerAliases

Added in API level 1

public abstract 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`	`String`: the key algorithm type name
`issuers`	`Principal`: the list of acceptable CA issuer subject names or null if it does not matter which issuers are used.

Returns
`String[]`	an array of the matching alias names, or null if there were no matches.
