zero-overhead Win32 Crypt32 bindings for [Bun](https://bun.sh) on Windows.\r\n\r\n## Overview\r\n\r\n`@bun-win32/crypt32` exposes the `crypt32.dll` exports using [Bun](https://bun.sh)'s FFI. It provides a single class, `Crypt32`, which lazily binds native symbols on first use. You can optionally preload a subset or all symbols up-front via `Preload()`.\r\n\r\nThe bindings are strongly typed for a smooth DX in TypeScript.\r\n\r\n## Features\r\n\r\n- [Bun](https://bun.sh)-first ergonomics on Windows 10/11.\r\n- Direct FFI to `crypt32.dll` (certificate stores, certificate chains, encoding/decoding, data protection, signing, and more).\r\n- In-source docs in `structs/Crypt32.ts` with links to Microsoft Docs.\r\n- Lazy binding on first call; optional eager preload (`Crypt32.Preload()`).\r\n- No wrapper overhead; calls map 1:1 to native APIs.\r\n- Strongly-typed Win32 aliases (see `types/Crypt32.ts`).\r\n\r\n## Requirements\r\n\r\n- [Bun](https://bun.sh) runtime\r\n- Windows 10 or later\r\n\r\n## Installation\r\n\r\n```sh\r\nbun add @bun-win32/crypt32\r\n```\r\n\r\n## Quick Start\r\n\r\n```ts\r\nimport Crypt32 from '@bun-win32/crypt32';\r\n\r\n// Open the current user's personal certificate store\r\nconst store = Crypt32.CertOpenSystemStoreW(0n, Buffer.from('MY\\0', 'utf16le').ptr);\r\n\r\n// Enumerate certificates\r\nlet cert = Crypt32.CertEnumCertificatesInStore(store, null);\r\nlet count = 0;\r\nwhile (cert !== null) {\r\n count++;\r\n cert = Crypt32.CertEnumCertificatesInStore(store, cert);\r\n}\r\nconsole.log('Found %d certificates in MY store', count);\r\n\r\nCrypt32.CertCloseStore(store, 0);\r\n```\r\n\r\n> [!NOTE]\r\n> AI agents: see `AI.md` for the package binding contract and source-navigation guidance. It explains how to use the package without scanning the entire implementation.\r\n\r\n## Examples\r\n\r\nRun the included examples:\r\n\r\n```sh\r\nbun run example\r\n```\r\n\r\n## Notes\r\n\r\n- Either rely on lazy binding or call `Crypt32.Preload()`.\r\n- Windows only. Bun runtime required.\n- **SAL types & naming:** nullability is in the **type** — `Optional` (formally optional, SAL `_*opt_`) and `Nullable` (plain `[in]`/`[out]` the docs say can be NULL), the null sentinel derived from `T` (`null` for pointers `LP*`/`P*`, `0n` for handles/by-value addresses); direction is in the **parameter name** — `_out` (`_Out_`), `_in_out` (`_Inout_`), `_In_` bare. See `AI.md` and the repo `AGENTS.md`.\n","readmeFilename":"README.md"}
