iOS 7 app to create a password protected PDF or DOC file I would like to create a file on my iPad, password protect it, and email it to a colleague.  Is there a way to do this?  It would have to be in a format that is readable by others, like a password protected PDF file or a password protected Word file.
molgar is right, just open in Pages app, set password and export as any file format and email it.

Set password


Open in another app


Choose export format



If you wanna email any file just download MailAnyFile from iOS AppStore.
