Update of /cvsroot/neuclear/neuclear-id/src/java/org/neuclear/passphraseagents
In directory sc8-pr-cvs1:/tmp/cvs-serv29589/src/java/org/neuclear/passphraseagents
Added Files:
CommandLineAgent.java GuiDialogAgent.java PassPhraseAgent.java
neuclear.png
Log Message:
Refactored the whole signing process. Now we have an interface called Signer which is the old SignerStore.
To use it you pass a byte array and an alias. The sign method then returns the signature.
If a Signer needs a passphrase it uses a PassPhraseAgent to present a dialogue box, read it from a command line etc.
This new Signer pattern allows us to use secure signing hardware such as N-Cipher in the future for server applications as well
as SmartCards for end user applications.

The GuiDialogAgent now works. It simply presents itself as a simple modal dialog box asking for a passphrase.
The two Signer implementations both use it for the passphrase.
