+## About
+
+The goal of this plugin is to provide a fast and powerful cryptographic functions by calling native libraries. On Android, it uses [javax.cypto](https://developer.android.com/reference/javax/crypto/package-summary), and on iOS, it uses [CommonCrypto](https://opensource.apple.com/source/CommonCrypto/) and [CryptoKit](https://developer.apple.com/documentation/cryptokit/)
+
+I started this projet because I wanted to add cryptographic functions on a Flutter app. But I faced a problem with the well-known [Pointy Castle](https://pub.dev/packages/pointycastle) library: the performance was very poor. Here some benchmarks and comparison:
+
+![](resources/benchmarks.png)
+
+For comparison, on a *iPhone 13*, you can encrypt/decrypt a message of **2MiB** in **~5.6s** with PointyCastle and in **~40ms** with NativeCrypto. And on an *OnePlus 5*, you can encrypt/decrypt a message of **50MiB** in **~6min30** with PointyCastle and in less than **~1s** with NativeCrypto.
+
+In short, NativeCrypto is incomparable with PointyCastle.
+
+## Usage
+
+First, check compatibility with your targets.
+
+| iOS | Android | MacOS | Linux | Windows | Web |
+| --- | ------- | ----- | ----- | ------- | --- |
+| ✅  | ✅      | ❌     | ❌     | ❌      | ❌  |
+
+#### Hash
+
+To digest a message, you can use the following function:
+
+```dart
+Uint8List hash = await HashAlgorithm.sha256.digest(message);
+```
+
+> In NativeCrypto, you can use the following hash functions: SHA-256, SHA-384, SHA-512
+
+#### Keys
+
+You can build a `SecretKey` from a utf8, base64, base16 (hex) strings or raw bytes. You can also generate a SecretKey from secure random.
+
+```dart
+SecretKey secretKey = SecretKey(Uint8List.fromList([0x73, 0x65, 0x63, 0x72, 0x65, 0x74]));
+SecretKey secretKey = SecretKey.fromUtf8('secret');
+SecretKey secretKey = SecretKey.fromBase64('c2VjcmV0');
+SecretKey secretKey = SecretKey.fromBase16('63657274');
+SecretKey secretKey = await SecretKey.fromSecureRandom(256);
+```
+
+#### Key derivation
+
+You can derive a `SecretKey` using **PBKDF2**.
+
+First, you need to initialize a `Pbkdf2` object.
+
+```dart
+Pbkdf2 pbkdf2 = Pbkdf2(
+    keyBytesCount: 32,
+    iterations: 1000,
+    algorithm: HashAlgorithm.sha512,
+);
+```
+
+Then, you can derive a `SecretKey` from a password and salt.
+
+```dart
+SecretKey secretKey = await pbkdf2.derive(password: password, salt: 'salt');
+```
+
+> In NativeCrypto, you can use the following key derivation function: PBKDF2
+
+#### Cipher
+
+And now, you can use the `SecretKey` to encrypt/decrypt a message.
+
+First, you need to initialize a `Cipher` object.
+
+```dart
+AES cipher = AES(secretKey);
+```
+
+Then, you can encrypt your message.
+
+```dart
+CipherTextWrapper wrapper = await cipher.encrypt(message);
+
+CipherText cipherText = wrapper.unwrap<CipherText>();
+// same as
+CipherText cipherText = wrapper.single;
+
+// or
+
+List<CipherText> cipherTexts = wrapper.unwrap<List<CipherText>>();
+// same as
+List<CipherText> cipherTexts = wrapper.list;
+```
+
+After an encryption you obtain a `CipherTextWrapper` which contains `CipherText` or `List<CipherText>` depending on the message size. It's up to you to know how to unwrap the `CipherTextWrapper` depending the chunk size you configured.
+
+Uppon receiving encrypted message, you can decrypt it.
+You have to reconstruct the wrapper before decrypting.
+
+```dart
+CipherTextWrapper wrapper = CipherTextWrapper.fromBytes(
+    data,
+    ivLength: AESMode.gcm.ivLength,
+    tagLength: AESMode.gcm.tagLength,
+);
+```
+
+Then, you can decrypt your message.
+
+```dart
+Uint8List message = await cipher.decrypt(wrapper);
+```

-# native_crypto
-
-A new flutter plugin project.
-
-## Getting Started
-
-This project is a starting point for a Flutter
-[plug-in package](https://flutter.dev/developing-packages/),
-a specialized package that includes platform-specific implementation code for
-Android and/or iOS.
-
-For help getting started with Flutter, view our
-[online documentation](https://flutter.dev/docs), which offers tutorials,
-samples, guidance on mobile development, and a full API reference.
-
-The plugin project was generated without specifying the `--platforms` flag, no platforms are currently supported.
-To add platforms, run `flutter create -t plugin --platforms <platforms> .` under the same
-directory. You can also find a detailed instruction on how to add platforms in the `pubspec.yaml` at https://flutter.dev/docs/development/packages-and-plugins/developing-packages#plugin-platforms.

-You can customize the launch screen with your own desired assets by replacing the image files in this directory.
-
-You can also do it by opening your Flutter project's Xcode project with `open ios/Runner.xcworkspace`, selecting `Runner/Assets.xcassets` in the Project Navigator and dropping in the desired images.

-
-A new flutter plugin project.
-
-## Getting Started
-
-This project is a starting point for a Flutter
-[plug-in package](https://flutter.dev/developing-packages/),
-a specialized package that includes platform-specific implementation code for
-Android and/or iOS.
-
-For help getting started with Flutter, view our
-[online documentation](https://flutter.dev/docs), which offers tutorials,
-samples, guidance on mobile development, and a full API reference.
-
-The plugin project was generated without specifying the `--platforms` flag, no platforms are currently supported.
-To add platforms, run `flutter create -t plugin --platforms <platforms> .` under the same
-directory. You can also find a detailed instruction on how to add platforms in the `pubspec.yaml` at https://flutter.dev/docs/development/packages-and-plugins/developing-packages#plugin-platforms.

-/// Base class for platform interfaces.
-///
-/// Provides a static helper method for ensuring that platform interfaces are
-/// implemented using `extends` instead of `implements`.
-///
-/// Platform interface classes are expected to have a private static token object which will be
-/// be passed to [verifyToken] along with a platform interface object for verification.
-///
-/// Sample usage:
-///
-/// ```dart
-/// abstract class UrlLauncherPlatform extends PlatformInterface {

-///
-///   static UrlLauncherPlatform _instance = MethodChannelUrlLauncher();

-///     PlatformInterface.verifyToken(instance, _token);
-///     _instance = instance;
-///   }
-///
-///  }
-/// ```

-/// Mockito mocks of platform interfaces will fail the verification, in test code only it is possible

+## About
+
+The goal of this plugin is to provide a fast and powerful cryptographic functions by calling native libraries. On Android, it uses [javax.cypto](https://developer.android.com/reference/javax/crypto/package-summary), and on iOS, it uses [CommonCrypto](https://opensource.apple.com/source/CommonCrypto/) and [CryptoKit](https://developer.apple.com/documentation/cryptokit/)
+
+I started this projet because I wanted to add cryptographic functions on a Flutter app. But I faced a problem with the well-known [Pointy Castle](https://pub.dev/packages/pointycastle) library: the performance was very poor. Here some benchmarks and comparison:
+
+![](resources/benchmarks.png)
+
+For comparison, on a *iPhone 13*, you can encrypt/decrypt a message of **2MiB** in **~5.6s** with PointyCastle and in **~40ms** with NativeCrypto. And on an *OnePlus 5*, you can encrypt/decrypt a message of **50MiB** in **~6min30** with PointyCastle and in less than **~1s** with NativeCrypto.
+
+In short, NativeCrypto is incomparable with PointyCastle.
+
+## Usage
+
+First, check compatibility with your targets.
+
+| iOS | Android | MacOS | Linux | Windows | Web |
+| --- | ------- | ----- | ----- | ------- | --- |
+| ✅  | ✅      | ❌     | ❌     | ❌      | ❌  |
+
+#### Hash
+
+To digest a message, you can use the following function:
+
+```dart
+Uint8List hash = await HashAlgorithm.sha256.digest(message);
+```
+
+> In NativeCrypto, you can use the following hash functions: SHA-256, SHA-384, SHA-512
+
+#### Keys
+
+You can build a `SecretKey` from a utf8, base64, base16 (hex) strings or raw bytes. You can also generate a SecretKey from secure random.
+
+```dart
+SecretKey secretKey = SecretKey(Uint8List.fromList([0x73, 0x65, 0x63, 0x72, 0x65, 0x74]));
+SecretKey secretKey = SecretKey.fromUtf8('secret');
+SecretKey secretKey = SecretKey.fromBase64('c2VjcmV0');
+SecretKey secretKey = SecretKey.fromBase16('63657274');
+SecretKey secretKey = await SecretKey.fromSecureRandom(256);
+```
+
+#### Key derivation
+
+You can derive a `SecretKey` using **PBKDF2**.
+
+First, you need to initialize a `Pbkdf2` object.
+
+```dart
+Pbkdf2 pbkdf2 = Pbkdf2(
+    keyBytesCount: 32,
+    iterations: 1000,
+    algorithm: HashAlgorithm.sha512,
+);
+```
+
+Then, you can derive a `SecretKey` from a password and salt.
+
+```dart
+SecretKey secretKey = await pbkdf2.derive(password: password, salt: 'salt');
+```
+
+> In NativeCrypto, you can use the following key derivation function: PBKDF2
+
+#### Cipher
+
+And now, you can use the `SecretKey` to encrypt/decrypt a message.
+
+First, you need to initialize a `Cipher` object.
+
+```dart
+AES cipher = AES(secretKey);
+```
+
+Then, you can encrypt your message.
+
+```dart
+CipherTextWrapper wrapper = await cipher.encrypt(message);
+
+CipherText cipherText = wrapper.unwrap<CipherText>();
+// same as
+CipherText cipherText = wrapper.single;
+
+// or
+
+List<CipherText> cipherTexts = wrapper.unwrap<List<CipherText>>();
+// same as
+List<CipherText> cipherTexts = wrapper.list;
+```
+
+After an encryption you obtain a `CipherTextWrapper` which contains `CipherText` or `List<CipherText>` depending on the message size. It's up to you to know how to unwrap the `CipherTextWrapper` depending the chunk size you configured.
+
+Uppon receiving encrypted message, you can decrypt it.
+You have to reconstruct the wrapper before decrypting.
+
+```dart
+CipherTextWrapper wrapper = CipherTextWrapper.fromBytes(
+    data,
+    ivLength: AESMode.gcm.ivLength,
+    tagLength: AESMode.gcm.tagLength,
+);
+```
+
+Then, you can decrypt your message.
+
+```dart
+Uint8List message = await cipher.decrypt(wrapper);
+```
