Use the RichEditControl for WPF to load and save password-encrypted files.

WPF Rich Text Editor - Document Encryption

The following sample project shows how to use the RichEditControl for WPF to load and save password-encrypted files. You can specify a password and an encryption type on the left pane and export the result to DOCX or DOC format. When a user re-opens the file with a new password, the RichEditControl.EncryptedFilePasswordRequested and RichEditControl.EncryptedFilePasswordCheckFailed events occur. If the user cancels the operation or exceeds the number of attempts to enter the password, RichEditControl shows the exception message.
