SECURITY KEY: mask encryption key during entry

[jesscmoore]

Describe the Bug

When entering the encryption key into the security dialog, the key value is briefly shown during entry, such that a keen observer or video recording can determine the encryption key when it is being entered during a demo. The encryption key should be fully masked during entry, as it is when the user enters their password.

Masking of password entry is also needed in the Solid Setup Wizard.

To Reproduce

Eg. notepod app
Login, then enter encryption key

Expected Behaviour

No brief disclosure of the key value before masking.

Where has the issue been observed:

• Android

Closing Criteria

Checklist for closing the issue:

• No errors from make prep
• All tests pass make qtest
• It is not possible to see encryption key characters during entry.

I've not been able to reproduce this on Linux. Tried notepod, example, bookoflife. None of them show the key as I type. Which dialog do you see this happening on. Could it be an Apple thing?
