securing adhoc distribution ipa file

Hi,

I'm new in iOS development. I use adhoc distribution to provide an early version of an app to friends. Due to easier updating, I would like to provide over-the-air installation via manifest and ipa file download. Because Safari do not send cookies while downloading manifest and ipa files, I have an issue providing the files behind a login. Therefore I think about providing the files without a login. Now to my question: Is there any reason to NOT provide the files (especially the adhoc-distribution ipa file) to public internet? Are there any information (account, certificates, signings, ...) in this file beside the code of the app itself, that should remain private?

Greetings Matthias
