This will download and decompress the kernelcache for an iPhone XS running iOS 12.1 behind a corporate proxy
$ ipsw download --proxy http://proxy.org:[PORT] --device iPhone11,2 --build 16B92To disable cert verification

$ ipsw kernel decompress kernelcache.release.iphone11I am playing with the idea of diffing kernelcaches by creating directory structures of Apple's src from assert strings.
Then you could use git diff or something to get a quick high level view of what Apple has changed by seeing new files being added or removed as well as seeing the line numbers of the assert strings move around.
$ ipsw kernel diff kernelcache.release.iphone11You can see an example of what this outputs HERE
- use https://github.com/gocolly/colly
- create offline copy of ipsw.me API
- download simultaniously to decrease total time (need to limit concurrent downloads and 17+ at a time could be bad)
