Class SigningUtility

java.lang.Object
  issrg.acm.SigningUtility

All Implemented Interfaces:

Utility, Signer

Direct Known Subclasses:

DefaultSigningUtility, SimpleSigningUtility

public abstract class SigningUtility
extends java.lang.Object
implements Utility, Signer

This is a base class for signing things.

The state diagram for the caller could be displayed in the following way:

 
    .---------------[logout]--------------.
 
    |                                     |
 
    v                                     |
 
.-------.            .-----------------.--'
 
| start |--[login]-->| constant signer |----------------.
 
`-------' .--------->`-----------------'                |
 
          |                                             |
 
          `--[getSigningAlgorithmID, sign, isLoggedIn]--'
 

Note that in ``constant signer`` state the Manager must ensure the signer does not change after logging in.

In ISSRG implementation of the Manager the Issuer DN and Issuer BCID input fields are disabled for editing and are present only for observation of the current value; however, before signing the Manager puts there the actual values obtained from the PKC.

The ISSRG implementation logs the user out after each signing to ensure better security of the signing process.
