We intend to distribute a mobile app to a customer who is a retail wholesaler with franchisee/store owners. Platforms supported will be Android and iOS. For the iOS distribution we prefer that the app is distributed using the iOS enterprise program rather than to the retail app store. One of the restrictions which I have read about (having never "published" an enterprise iOS app in the past) is that the link to download the IPA or .plist file should be provided via HTTPS/SSL. This means that the serving URL must have an SSL cert bound to it and not merely a self signed cert. Apparently this restriction is relatively new (perhaps iOS 8 or 9)
I've noticed that Azure provide so-called wildcard SSL certs for subdomains of their Azure Website or Azure Web Services offerings. Would such a wildcard SSL certificate be adequate to address the minimal requirements for the iOS device to validate the download of the app ? Obviously, what I am thinking here is that we host the link to latest app download from a Azure web app/web site. The app would obviously have been built with the correct provisioning profile and app id required for enterprise deployment.
