@Deprecated(since="1.2", forRemoval=true) public abstract class Signer extends Identity
Deprecated, for removal: This API element is subject to removal in a future version.
This class is deprecated and subject to removal in a future version of Java SE. It has been replaced by java.security.KeyStore, the java.security.cert package, and java.security.Principal.
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.
