Here are instructions and advice for setting up and managing a Cydia repository. For context, Cydia uses an adapted version of Debian APT (Advanced Packaging Tool) to manage packages.

The authoritative guide to setting up a Cydia APT repository is saurik's post on the subject.
Public since July 3rd 2015 in saurik's tweet, it is possible to link to a repository or package from a url that Cydia can pick up.
To link to a repository, make an anchor on your site to
To link to a package, make an anchor on your site to
Replacing http://apt.saurik.com/beta/itsamystery/ and com.saurik.mystery to the target repository and package.
If the repository is not on the list Cydia will ask to add it. It will then take you to the package list (if linked to a repository) or to the specified package (if linked to a package).

Quick and dirty summary
First thing is, you'll need a web host. It could be anything, like GitHub pages (which is what most people do these days).
The basic idea is that you have two files in your server, Packages and Release. Packages must be bzipped and named Packages.bz2, and optionally Release may be also. Packages contains all of the information related to the different packages on your server (and where to download them, more on that later) and Release contains all of the information related to your server (like the name, description, etc).
If you want to see examples of Packages and Release files, you can see the cached files from your installed repos at /var/lib/apt/lists (note they can be quite large).
Put the file CydiaIcon.png at the root of your repository. It is displayed at 32x32, and it would be best for the file to be at Retina resolution (64x64 for @2x and 96x96 for @3x).
NOTE: Static webhosts (like Github Pages) won't work for private repos. You'll need a server that has some way to let you process requests server-side, e.g. PHP, node.js, Go, Django, etc.
Payment Provider API
All current package managers (with the exception of Cydia) support Payment Provider API, which can be used for purposes other than payment/checkout systems.
You can use a username and password system through Cydia's depiction system, where the user enters their username and password in the depiction page, and then is authorized to download the package.
Password Protection Examples
You can also restrict access based on UDID. Cydia sends the user's UDID via the X-Unique-ID HTTP header, so your server could check that against a database in order to ensure that the user has rightful access.
Pitfalls of UDID Protection
UDID-protected repos are not very secure. UDID's can be easily faked since there is nothing to say whether it's legitimate or spoofed since it's sent as an HTTP header (
X-Unique-ID), and these are sent with every Cydia support email. There have been public UDID leaks that pirate repositories are known to brute-force packages with. An unfortunate number of repositories, and Cydia Store, use it despite its misuse being bad enough that it was banned from the App Store in 2012. You should not consider protection by UDID completely secure; while it works and is simple to implement, it's like a fingerprint: if it's compromised by bad guys, it's hard to change it.
