The Invalid Mac crash had no test standing between it and a repeat, so this adds one that reproduces it. GiftWrapMessageTest builds real NIP-59 wraps with real secp256k1 rather than recorded fixtures. The property under test is the key agreement itself — whether ECDH(ourPriv, ephemeralPub) can stand in for the conversation key the wrap was sealed under — and a fixture would only prove that the fixture still parses. Three cases carry the regression: - someone else's mail comes back null rather than throwing - not even the sender can reopen what they sent - isAddressedTo answers exactly what unsealing would Checked against the reverted fix, those three fail with the production exception verbatim (java.lang.IllegalStateException: Invalid Mac: Calculated bf2e6480…), while the two describing behaviour that never broke — the happy path, and isAddressedTo's reading of the p tag — stay green. A test that cannot fail against the bug it names is not worth the run time, so the split matters. The last of the three is the one guarding the fix's structure rather than its outcome. NostrDao decides whether to index on isAddressedTo, then throws GiftWrapUnsealException if decryptGiftWrapSeal returns null anyway; those two answers have to agree for either path to be correct. If they drift, the DAO either skips mail we can open or resumes rolling back transactions, and neither shows up as a failure anywhere near the change that caused it. commonTest gains kotlinx-coroutines-test for runTest. decryptGiftWrapSeal is suspending, runBlocking does not exist in common code, and every layer worth testing below the ViewModels — DAOs, repositories, the model's crypto — is suspending too, so the dependency pays for more than this file.

This is a Kotlin Multiplatform project targeting Android, iOS, Desktop (JVM).
-
/composeApp is for code that will be shared across your Compose Multiplatform applications. It contains several subfolders:
- commonMain is for code that’s common for all targets.
- Other folders are for Kotlin code that will be compiled for only the platform indicated in the folder name. For example, if you want to use Apple’s CoreCrypto for the iOS part of your Kotlin app, the iosMain folder would be the right place for such calls. Similarly, if you want to edit the Desktop (JVM) specific part, the jvmMain folder is the appropriate location.
-
/iosApp contains iOS applications. Even if you’re sharing your UI with Compose Multiplatform, you need this entry point for your iOS app. This is also where you should add SwiftUI code for your project.
Build and Run Android Application
To build and run the development version of the Android app, use the run configuration from the run widget in your IDE’s toolbar or build it directly from the terminal:
- on macOS/Linux
./gradlew :composeApp:assembleDebug - on Windows
.\gradlew.bat :composeApp:assembleDebug
Build and Run Desktop (JVM) Application
To build and run the development version of the desktop app, use the run configuration from the run widget in your IDE’s toolbar or run it directly from the terminal:
- on macOS/Linux
./gradlew :composeApp:run - on Windows
.\gradlew.bat :composeApp:run
Build and Run iOS Application
To build and run the development version of the iOS app, use the run configuration from the run widget in your IDE’s toolbar or open the /iosApp directory in Xcode and run it from there.
