Offline FairPlay App Store IPA decryption with independent key derivation
A C-based tool that decrypts FairPlay-encrypted App Store IPA files offline. Using a 16-byte credential retrieved from a jailbroken device that owns the app, it derives page keys from each IPA's SINF and SUPF records, decrypts encrypted arm64 Mach-O pages, and clears cryptid — running on macOS and Linux.
Why now: It's rapidly gaining stars as a newly released repo, notable for offline decryption with independent key derivation rather than relying on live device decryption.
Who it is for: iOS security researchers and jailbreak enthusiasts who want to decrypt App Store apps they own for analysis or archival.
