This class is no longer used. Its functionality has been replaced by java.security.KeyStore, the java.security.cert package, and java.security.Principal.

@Deprecated
public abstract class Signer
extends Identity

This class is used to represent an Identity that can also digitally sign data.

The management of a signer's private keys is an important and sensitive issue that should be handled by subclasses as appropriate to their intended use.

Signer

protected Signer()

已过时。

Creates a signer. This constructor should only be used for serialization.

Signer

public Signer(String name)

已过时。

Creates a signer with the specified identity name.

参数:

name - the identity name.

Signer

public Signer(String name,
              IdentityScope scope)
       throws KeyManagementException

已过时。

Creates a signer with the specified identity name and scope.

参数:

name - the identity name.

scope - the scope of the identity.

抛出:

KeyManagementException - if there is already an identity with the same name in the scope.

方法详细资料

getPrivateKey

public PrivateKey getPrivateKey()

已过时。

Returns this signer's private key.

First, if there is a security manager, its checkSecurityAccess method is called with "getSignerPrivateKey" as its argument to see if it's ok to return the private key.

返回:

this signer's private key, or null if the private key has not yet been set.

抛出:

SecurityException - if a security manager exists and its checkSecurityAccess method doesn't allow returning the private key.

setKeyPair

public final void setKeyPair(KeyPair pair)
                      throws InvalidParameterException,
                             KeyException

已过时。

Sets the key pair (public key and private key) for this signer.

First, if there is a security manager, its checkSecurityAccess method is called with "setSignerKeyPair" as its argument to see if it's ok to set the key pair.

参数:

pair - an initialized key pair.

抛出:

InvalidParameterException - if the key pair is not properly initialized.

KeyException - if the key pair cannot be set for any other reason.

SecurityException - if a security manager exists and its checkSecurityAccess method doesn't allow setting the key pair.
