opencard.opt.signature
Interface KeyGenerationCardService
- public abstract interface KeyGenerationCardService
- extends SignatureCardService
KeyGenerationCardService
The SignatureCardService offers methods to generate and verify a signature
as well as key import, verification and generation methods. Many smartcard
applications will work with existing keys imported during initialization or
personalization instead of importing/generating them at runtime. Thus the
functionality for
- signature generation and verification
- key import and verification
- key generation
is split into three interfaces "SignatureCardService", "KeyImportCardService"
and "KeyGenerationCardService". Card service realizations of these interfaces
need only implement the functionality needed by the application or supported
by the specific card. This solution also offers potential for downsizing
opencard for use in embedded devises with small memory resources.
