Microsoft Office InfoPath forms are stored in clear-text and thus considered insecure, especially if you have an option to enter the Password. In this article, Wong examines how to enable a user to enter a password into an InfoPath form and use it to encrypt and decrypt sensitive InfoPath form fields without saving the password.

Microsoft Office InfoPath 2003 is based on XML technology.  All data within InfoPath forms, including sensitive data, is saved in clear text and remains readable to anyone who can access the form’s data.  Adding password fields to a form would therefore expose any passwords entered and saved along with the form's data.

This article builds on the concept of encrypting and decrypting data when saving an InfoPath form.  This concept was first discussed in an MSDN article called "Extending the Save Functionality in InfoPath 2003".  This article assumes that you have adequate familiarity with Microsoft InfoPath 2003 and Visual C# .NET.
