Class PasswordProvider

java.lang.Object

de.intarsys.pdf.crypt.PasswordProvider

public class PasswordProvider
extends Object

A VM singleton for the PDF related IPasswordProvider.

Using this factory one can implement different strategies for the IAuthenticationHandler to receive its passwords.

First, a password attached to the document itself (via the options when opening) can be looked up.
Second, an IPasswordProvider attached to the document itself (via the options when opening) can be looked up.
Third, a global IPasswordProvider attached to the current thread can be looked up.
Fourth, a globally unique IPasswordProvider can be looked up.

While an ISecurityHandler or IAuthenticationHandler does not need to use these features, the standard implementations do.
