Features

One buffer type from Rust to TypeScript.

  • Rust-powered

    Cryptography written or wrapped in Rust and compiled to WebAssembly for native-grade performance.

  • Synchronous loading

    WASM is inlined as base64, so packages load like ordinary JavaScript — no async imports, no top-level await.

  • Typed buffers

    A common WebBuf format and FixedBuf<N> give every package a shared, type-safe buffer surface.
