Free embedded database which support encryption (.NET)

Question

I'm looking for a free embedded database for .NET (C#), which supports encryption. Preferably some sort of TDE (Transparent Data Encryption) using good encryption protocols (like AES 256).

Thank you for your time and answers.

Answer 1

Sadly nobody answered. Well later on I found out that SQL CE 3.5 and 4.0 both support encryption, are free and embedded and support C# (.NET).
