Download the SDK

One tarball holds everything you need to protect a Rust program or a WebAssembly module and drive it from its host.

Moving to GitHub releases. The SDK is published here as a tarball for now. It will move to GitHub releases (and crates on a registry) without changing the crate names or APIs. The checksums file at /downloads/SHA256SUMS stays authoritative for every version published on this site.

What's inside

Path	What
`lease/`	`sigil-lease`: the verifier. `no_std` + `alloc`, `#![forbid(unsafe_code)]`. Compile it into your module or program. Feature `std` adds clock helpers for native hosts.
`client/`	`sigil-client`: activation, lease cache, renewal and deactivation for native Rust hosts (HTTPS via `ureq` + rustls).
`cli/`	`sigil-verify`: verify a lease from the command line, for support.
`examples/licensed-app/`	The quickstart's native program. Replace its `sigil-keys.json` with your application's.
`examples/wasm-module/`	A `no_std` WASM module with no imports, gated by a `Gate`, with a JS loader and a build script that checks the binary.
`js/`	`@sigil/sdk`: the JavaScript host SDK for extensions and Node (activation, `chrome.storage`/file cache, renewal, `unlock()`).
`README.md`, `NOTICE`	Quick reference and licensing terms.

Use it from your project

Reference the crates by path from your Cargo.toml:

Cargo.tomltoml

[dependencies]
sigil-lease = { path = "../sigil-sdk-rust-0.2.0/lease" }                     # WASM modules
sigil-lease = { path = "../sigil-sdk-rust-0.2.0/lease", features = ["std"] }  # native programs
sigil-client = { path = "../sigil-sdk-rust-0.2.0/client" }                   # native programs

Pick one of the two sigil-lease lines. For a JavaScript host, copy js/ into your project, or install it with npm install ./sigil-sdk-rust-0.2.0/js.

Versions

Version	Changes
`0.2.0`	The verifier is Rust only (the Go SDK is retired). `no_std`, runs in modules with no imports: the host passes `now` and the platform. Adds `sigil-client` for native hosts. Stable numeric error codes.

Lease protocol v1 is unchanged, so leases issued for earlier builds verify with this one.
