| 37 | * This abstract class is the wrapper for the cryptographic functionality | |
| 38 | * required to validate digital signatures. | |
| 39 | * | |
| 40 | * <p>Note that this somewhat duplicates the other interface, | |
| 41 | * issrg.security.Verifier. This double wrapping allows to integrate the | |
| 42 | * signature verification at different levels. SignatureVerifier interface | |
| 43 | * has smaller demands, e.g. it does not require the underlying implementation | |
| 44 | * to have access to the actual Verification Certificates, whilst the | |
| 45 | * issrg.security.Verifier requires the implementation to be able to provide the | |
| 46 | * signature verification certificates. The Verifier interface is more generic, | |
| 47 | * but may be harder to implement. | |
