Okay, I admit I'm still learning this. Let's say I had a function rot13(data,number) and using MVD and QtSql I want to encrypt one or more fields when they are written to disk using the built-in SQLite engine.
Is there a method I can override, or perhaps a way to create a custom view that would intercept all writes, and apply my rot13 function to the data before it gets written? I understand that this would be slow (unless using a compiled library like pycrypto), and I understand the need to use hashes vs encryption to do things like lookups. My goal is to have some or all sensitive fields encrypted with some sort of password, or better yet a password encrypted key, to protect the locally stored data. Sample code would be greatly appreciated. Thanks, David
