Appearance of Java Security dialog

问题:

The Java Security dialog is shown when loading a signed applet.

What does the Java Security dialog look like?

回答1:

The security dialog might appear differently (and have different text) depending on the circumstances, but it looks roughly as above.

If the 'digital signature cannot be verified' as in that message in the dialog, then:

• Always trust will default to false.
• It will be ignored even if selected.
• No Name or Publisher will appear. That image shows the prompt as it appears in older JREs.

Here is how the NASA World Wind prompt appears in a Java 7 JRE for a verified certificate that has expired. The plug-in will also not tick the Always allow check-box by default.
