Deprecated.
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 Its functionality has been replaced by java.security.KeyStore, the java.security.cert package, and java.security.Principal.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.

    Returns:
    this signer's private key, or null if the private key has not yet been set.
    
    Throws:
    
    SecurityException - if a security manager exists and its checkSecurityAccess method doesn't allow returning the private key.
