What's nonce entanglement?

Beginning with devices using an A12 SoC or higher, Apple introduced nonce entangling.

• This meant that, when saving SHSH blobs, a nonce generator would generate a different ApNonce for each device.
• When saving SHSH blobs for an A12+ device, you now must find a generator-ApNonce pair for your device, then use that generator-ApNonce pair when saving SHSH blobs.
• After you have found a generator-ApNonce pair for your device, you can save it and re-use it whenever you save SHSH blobs again.

Getting a generator-ApNonce pair (jailbroken)

1. (iOS 14+ only) Install an iOS kernel r/w library.
   • On Taurine, install libkernrw.

• On unc0ver, install libkrw.

This code generates an HTML table based from a CSV file. This is from the tutorial by Christophe Viau.

In trying his code example, I discovered that the code doesn't work as-is, so I figured others might like to see a working d3.js example that did not rely on a pre-existing container HTML element.

The code remains the same except for some cosmetic tweaks.

The task of writing the CSS is left as an exercise for the reader.
