mdc-lite v0.1.0

mdc-lite v0.1.0

An embeddable, encrypted key-value store for the places a server can't reach — a watch face, a phone app, a background service. XChaCha20-Poly1305 for every value and every key name, a 5-function API, no runtime.

Get it

Download a prebuilt build below for your platform, or build from source — grab mdc-lite-v0.1.0-source.tar.gz (or clone the repo) and run cargo build --release; full per-platform build commands (including iOS/watchOS, which has no prebuilt binary here — see why below) are in docs.html and the crate README.

What's verified, honestly

Platform	Asset	Status
macOS (Apple Silicon)	mdc-lite-v0.1.0-macos-arm64.dylib	✅ Built natively here; cargo test (14/14) passing on this exact target
Windows x86_64	mdc-lite-v0.1.0-windows-x86_64.dll + import lib	⚠️ Cross-compiled and linked (mingw-w64) to a real PE32+ DLL; not executed — no Wine available to run a Windows binary on macOS
Android arm64-v8a / armeabi-v7a / x86_64	mdc-lite-v0.1.0-android-*.so	⚠️ Built with the real Android NDK (r29) clang toolchain, ELF format confirmed; not executed — no emulator/device on hand
iOS / watchOS	—	🛠️ No prebuilt artifact. Apple requires linking against the real SDK, which ships only inside full Xcode.app — not a missing package, an Apple distribution requirement. Build from source on a Mac with full Xcode.
