Default Discussion: VBA Project Code Protection

hmm..
it's worse than you think...

Workbook and Worksheet protection encrypt the stored data.
(Although the encryption algoritm for worksheet is absurdly weak)

VBA project protection does NOT encrypt the data, it merely prevents access
to it. Even if it had a strong algoritm:

As long as you dont use workbook protection (which DOES encrypt all contents
of the file), then the modules' data is saved in plain text and can by read
from the file with any hex editor, regardless of VBA password.

Also, let's restrict our scope to VBA projects.)



Let's talk about this.
Welcome anybody's idea, welcome especially someone in Microsoft.
