---

🏗 Build From Source

git clone https://github.com/CodeWorldBlog/ipasigncraft.git
cd ipasigncraft
open IPASignCraft.xcodeproj

Build using Xcode 16+.

---

🧱 Built With

• Swift
• SwiftUI
• Security.framework
• Apple's standard codesign tooling

---

🔒 Security Philosophy

IPASignCraft performs the signing process inside an isolated temporary macOS keychain session.

This ensures:

• No permanent certificate import into Login Keychain
• No modification of System Keychain
• No long-lived signing identity left on the machine
• Temporary signing artifacts are removed automatically after completion

A cleaner and safer workflow for Apple code-signing operations.

---

🔐 Certificate Handling

IPASignCraft never ships with certificates or provisioning profiles.

Users must provide their own Apple development assets locally during the signing process.
