npm package: @fork-anyone/sqlcipher
Description: Asynchronous, non-blocking SQLCipher bindings
Author: JourneyApps
Latest version: 5.3.8

Fork of [node-sqlite3](https://github.com/mapbox/node-sqlite3), modified to use [SQLCipher](https://www.zetetic.net/sqlcipher/).

While the `node-sqlite3` project does include support for compiling against sqlcipher, it requires manual work, and does not work out-of-the-box on Electron on Windows. This fork changes the default configuration to bundle SQLCipher directly, as well as OpenSSL where required.

## Supported platforms

Binaries are built against N-API 3 and 6, on MacOS, Windows (ia32 and x64) and Linux (x64).

Node 10+ and Electron 6+ is supported.

Other platforms/architectures may work by building from source - see the section below.

# Installation

```sh
yarn add "@journeyapps/sqlcipher"
# Or: npm install --save "@journeyapps/sqlcipher"
```

# Usage

``` js
var sqlite3 = require('@journeyapps/sqlcipher').verbose();
var db = new sqlite3.Database('test.db');

db.serialize(function() {
  // This is the default, but it is good to specify explicitly:
  db.run("PRAGMA cipher_compatibility = 4");

  // To open a database created with SQLCipher 3.x, use this:
  // db.run("PRAGMA cipher_compatibility = 3");

  db.run("PRAGMA key = 'mysecret'");
  db.run("CREATE TABLE lorem (info TEXT)");

  var stmt = db.prepare("INSERT INTO lorem VALUES (?)");
  for (var i = 0; i < 10; i++) {
      stmt.run("Ipsum " + i);
  }
  stmt.finalize();

  db.each("SELECT rowid AS id, info FROM lorem", function(err, row) {
      console.log(row.id + ": " + row.info);
  });
});

db.close();
```

# SQLCipher

A copy of the source for SQLCipher 4.4.2 is bundled, which is based on SQLite 3.33.0.

## Building from source.

Building from source when installing the package is only supported up to version 5.2.0.

The two pre-built versions (N-API 3 and N-API 6) cover all electron and node versions, so building from source should
not be required.

## Usage with electron-forge / electron-rebuild

[electron-forge](https://www.electronforge.io/) uses [electron-rebuild](https://github.com/electron/electron-rebuild) and attempts to rebuild this library from source by default, in a way
that is _not_ compatible with the way `node-pre-gyp` is used here.

The workaround is to disable the rebuilding:
1. If using Electron 11+, use a node version that supports N-API 6+ (v10.20.0+ / v12.17.0+ / v14.0.0).
2. After `npm install` / `yarn install`, make sure that the folder `node_modules/@journeyapps/sqlcipher/lib/binding/napi-v6-linux-x64` exists.
   If not, check the previous step again, remove the `node_modules` folder, and try again.
3. Disable rebuilding of this library using the `onlyModules` option of `electron-rebuild` in your `package.json`:

        "config": {
            "forge": {
                "electronRebuildConfig": {
                    "onlyModules": []  // Specify other native modules here if required
                }
            }
        }

Note: [electron-builder](https://www.electron.build/) does not appear to have this issue, and should work directly.
Similarly, using electron directly should just work, but do check that a compatible node version is used (see above). 

## OpenSSL

SQLCipher depends on OpenSSL.

For Windows, we bundle OpenSSL 1.1.1i. Binaries are generated using [vckpg](https://github.com/microsoft/vcpkg) (e.g., `.\vcpkg\vcpkg install openssl:x64-windows-static`).

On Mac we bundle OpenSSL 1.1.1l.

On Linux we dynamically link against the system OpenSSL.
