Requirements for packages to be featured as of February 24, 2019:

1. Either be a free Package or the user must be able to purchase it without needing to use or create an account with the payment processor [accounts should be made with the repo though] (NOT PayPal) [e.g. Stripe/Square/Fastspring/AliPay]
2. Must be approved by either the featured package review team or by a contributor to Sileo (Sileo contributors don't need approval for their own packages)
3. Must have a 16:9 ratio (1280x720 px minimum) banner that does not have the name of the package inside it
4. Must have an icon (250x250 px minimum)
5. Must be on either Chariz, Dynastic or Packix
6. Packages must use a native depiction with a banner in the depiction
7. For paid packages, there is no need to pay a cut to Sileo to get featured (payments are handled by the repo of your choice, as usual)
8. Tweaks can not contain malware or other unwanted behavior

Cryptiiiic

Unfortunately I have some bad news for downgrading.
Before I explain the bad news at the end of this post, I first need to introduce a background of iOS devices.
In iOS 16, Apple introduced a new firmware component known as Cryptex1. Technically, this is a "virtual" co-processor.
It's purpose is to allow Apple to push RSRs (Rapid Security Responses) which are separate from traditional iOS updates and can be installed much faster.
Like other firmwares, it also has a signing ticket locked to a cryptographic nonce (number-used-once).
We commonly refer to the Apple signing tickets as SHSH blobs.
Meaning the firmware can't be installed without a valid signing ticket as well as a matching nonce.
The "big two" components we deal with signing/nonces are AP and SEP. AP is basically the main device chip (Application Processor).
SEP is the security chip (Secure Enclave Processor).
With regards to APNonce, Apple conveniently gave us the com.apple.System.boot-nonce NVRAM property which we use to set the APNonce generator.
