Class DSAPrivateKey
java.lang.Object
|
+--opencard.opt.security.DSAPrivateKey
- public class DSAPrivateKey
- extends java.lang.Object
- implements java.security.interfaces.DSAPrivateKey
Contains a public DSA key.
Implements the java.security.interfaces.DSAPrivateKey interface
CardServices using PKA algorithms like SignatureCardService require
keys implementing the PrivateKey/PublicKey interface.
In this package OpenCard provides key classes for common algorithms
like RSA, DSA (or DES) that each concrete card service implementing
a card service interface should support instead of defining its own
key classes.
Only for new PKA algorithms that OpenCard does not yet support a
card service may define its own key classes.
