The following sample project shows how to use the WinForms Rich Text Editor 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 an exception message.
