-## Background
+---
 
-🤔 Why I started this project ?
+[[Changelog]](./CHANGELOG.md) | [[License]](./LICENSE)
-Because I faced a performance issue when I was using **PointyCastle**.
 
-It's quite simple, judge for yourself, these are times for AES256 encryption on an Android device (**Huawei P30 Pro**).
+---
 
-| Size | PointyCastle |
+## About
-|------|--------------|
-| 100 kB | 190 ms
-| 200 kB | 314 ms
-| 300 kB | 1138 ms
-| 400 kB | 2781 ms
-| 500 kB | 4691 ms
-| 600 kB | 7225 ms
-| 700 kB | 10264 ms
-| 800 kB | 13582 ms
-| 900 kB | 17607 ms
 
-> We notice that these times, in addition to being far too big, are **not even linear**.
+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/)
 
-## Performances
+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:
 
-⏱ On an **Android 10** device: **Huawei P30 Pro**
+![](resources/benchmarks.png)
 
-| Size | NativeCrypto |
+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.
-|------|--------------|
-| 1 mB | 27 ms
-| 2 mB | 43 ms
-| 3 mB | 78 ms
-| 4 mB | 93 ms
-| 5 mB | 100 ms
-| 10 mB | 229 ms
-| 50 mB | 779 ms
 
-## Installation
+In short, NativeCrypto is incomparable with PointyCastle.
 
-🚧 You can easely setup a Flutter project with this plugin.
+## Features
 
-Just add these lines in your **pubspec.yaml**:
+* Hash functions
+    - SHA-256
+    - SHA-384
+    - SHA-512
+* HMAC functions
+    - HMAC-SHA-256
+    - HMAC-SHA-384
+    - HMAC-SHA-512
+* Secure random
+* PBKDF2
+* AES
+    - Uint8List encryption/decryption
+    - File encryption/decryption
 
-```yaml
+## Quick start
-native_crypto:
-    git:
-        url: https://gogs.pointcheval.fr/hugo/native-crypto-flutter.git
-        ref: v0.0.x
-```
-
-> Replace "x" with the current version!
-
-Then in your code:
 
 ```dart
-// Symmetric crypto.
+import 'package:native_crypto/native_crypto.dart';
-import 'package:native_crypto/symmetric_crypto.dart';
 
-// To handle exceptions.
+Future<void> main() async {
-import 'package:native_crypto/exceptions.dart';
+    // Message to encrypt
+    final Uint8List message = 'Hello World!'.toBytes();
+    
+    // Ask user for a password
+    final String password = await getPassword();
+
+    // Initialize a PBKDF2 object
+    final Pbkdf2 pbkdf2 = Pbkdf2(
+        length: 32, // 32 bytes
+        iterations: 1000,
+        salt: 'salt'.toBytes(),
+        hashAlgorithm: HashAlgorithm.sha256,
+    );
+    
+    // Derive a secret key from the password
+    final SecretKey secretKey = await pbkdf2(password: password);
+
+    // Initialize an AES cipher
+    final AES cipher = AES(
+        key: secretKey,
+        mode: AESMode.gcm,
+        padding: AESPadding.none,
+    );
+
+    // Encrypt the message
+    final CipherText<AESCipherChunk> cipherText = await cipher.encrypt(message);
+
+    // Decrypt the message
+    final Uint8List decryptedMessage = await cipher.decrypt(cipherText);
+
+    // Verify and print the decrypted message
+    assert(listEquals(message, decryptedMessage));
+    
+    print(decryptedMessage.toStr());
+}
 ```
 
+Check the [example](./native_crypto/example) for a complete example.
+
+Please take a look a the compatibility table below to check if your target is supported.
+
+> Note: This **Flutter** example must run on a real device or a simulator.
+
 ## Usage
 
-To create an AES instance, and generate a key.
+#### Compatibility
 
-```dart
+First, check compatibility with your targets.
-AES aes = AES();
+
-await aes.init(KeySize.bits256)
+| iOS | Android | MacOS | Linux | Windows | Web |
+| --- | ------- | ----- | ----- | ------- | --- |
+| ✅  | ✅      | ❌     | ❌     | ❌      | ❌  |
+
+> Warning: NativeCrypto 0.2.0+ is not compatible with lower NativeCrypto versions. Especially, with NativeCrypto 0.0. X because the cipher mode is not the same. Now, NativeCrypto uses AES-GCM mode instead of AES-CBC mode. (See [Changelog](./CHANGELOG.md))
+
+NativeCrypto ciphertexts are formatted as follow:
+
+```
++------------------+--------------------+------------------+
+| Nonce (12 bytes) | Cipher text (n-28) |  Tag (16 bytes)  |
++------------------+--------------------+------------------+
 ```
 
-You can also generate key, then use it in AES.
+> Warning: If your data comes from another source, make sur to use the same format.
+
+#### Hash
+
+To digest a message, you'll need to initialize a Hasher object implementing `Hash` . Then, you can digest your message.
 
 ```dart
-Uint8List aeskey = await KeyGenerator().secretKey(keySize: KeySize.bits256);
+Hash hasher = Sha256();
-AES aes = AES(key: aeskey);
+Uint8List digest = await hasher.digest(message);
 ```
 
-You can create a key with PBKDF2.
+> In NativeCrypto, you can use the following hash functions: SHA-256, SHA-384, SHA-512
+
+#### HMAC
+
+To generate a HMAC, you'll need to initialize a `Hmac` object. Then, you can generate a HMAC from a message and a secret key.
 
 ```dart
-Uint8List key = await KeyGenerator().pbkdf2(password, salt, keyLength: 32, iteration: 10000, digest: Digest.sha256);
+Hmac hmac = HmacSha256();
-AES aes = AES(key: key);
+Uint8List hmac = await hmac.digest(message, secretKey);
 ```
 
-Then you can encrypt/decrypt data with this instance.
+> In NativeCrypto, you can use the following HMAC functions: HMAC-SHA-256, HMAC-SHA-384, HMAC-SHA-512
+
+#### Keys
+
+You can build a `SecretKey` from utf8, utf16, base64, base16 (hex) strings, int list or raw bytes. You can also generate a SecretKey from secure random.
 
 ```dart
-encryptedPayload = await aes.encrypt(data);
+SecretKey secretKey = SecretKey(bytes); // bytes is a Uint8List
-decryptedPayload = await aes.decrypt(encryptedPayload);
+SecretKey secretKey = SecretKey.fromUtf8('secret');
+SecretKet secretKey = SecretKey.fromUtf16('secret');
+SecretKey secretKey = SecretKey.fromBase64('c2VjcmV0');
+SecretKey secretKey = SecretKey.fromBase16('63657274');
+SecretKey secretKey = SecretKey.fromList([0x73, 0x65, 0x63, 0x72, 0x65, 0x74]);
+SecretKey secretKey = await SecretKey.fromSecureRandom(32); // 32 bytes
 ```
 
-Or you can also use AES on the fly with different keys.
+#### Key derivation
+
+You can derive a `SecretKey` using **PBKDF2**.
+
+First, you need to initialize a `Pbkdf2` object.
 
 ```dart
-Uint8List aeskey = await KeyGenerator().secretKey(keySize: KeySize.bits256);
+final Pbkdf2 pbkdf2 = Pbkdf2(
-encryptedPayload = await AES().encrypt(data, key: aeskey);
+    length: 32, // 32 bytes
-decryptedPayload = await AES().decrypt(encryptedPayload, key: aeskey);
+    iterations: 1000,
+    salt: salt.toBytes(),
+    hashAlgorithm: HashAlgorithm.sha256,
+);
 ```
 
-Available `enums` are:
+Then, you can derive a `SecretKey` from a password.
 
 ```dart
-enum KeySize { bits128, bits192, bits256 }
+SecretKey secretKey = await pbkdf2(password: password); 
-enum Digest { sha1, sha256, sha512 }
 ```
 
-`KeySizes` defines all available key sizes for generation.
+> Note: Pbkdf2 is a callable class. You can use it like a function.
 
-`Digest` defines all available digest for PBKDF2.
+#### Cipher
 
-## Example
+And now, you can use the `SecretKey` to encrypt/decrypt a message.
 
-🔍 Look in **example/lib/** for an example app.
+First, you need to initialize a `Cipher` object.
 
-## How
+```dart
+final AES cipher = AES(
+    key: key,
+    mode: AESMode.gcm,
+    padding: AESPadding.none,
+);
+```
 
-🔬 But how it is possible ??
+Then, you can encrypt your message.
 
-Using the native implementation of crypto libs available on each OS.
+```dart
+final CipherText<AESCipherChunk> cipherText = await cipher.encrypt(message); 
+```
 
-For **Android**:
+After an encryption you obtain a `CipherText` which contains chunks. You can get the underlying bytes with `cipherText.bytes` .
 
-* [javax.crypto](https://docs.oracle.com/javase/7/docs/api/javax/crypto/package-summary.html)
+Uppon receiving encrypted message `receivedData` , you can decrypt it.
-* [java.security](https://docs.oracle.com/javase/7/docs/api/java/security/package-summary.html)
+You have to reconstruct the ciphertext and the setup the chunk factory.
 
-For **iOS**:
+```dart
+final CipherText<AESCipherChunk> receivedCipherText CipherText(
+    receivedData,
+    chunkFactory: (bytes) => AESCipherChunk(
+        bytes,
+        ivLength: cipher.mode.ivLength,
+        tagLength: cipher.mode.tagLength,
+    ),
+),
+```
 
-* [CommonCrypto](https://developer.apple.com/library/archive/documentation/Security/Conceptual/cryptoservices/Introduction/Introduction.html)
+Then, you can decrypt your message.
 
-## Todos
+```dart
+Uint8List message = await cipher.decrypt(receivedCipherText);
+```
 
-🚀 You can contribute to this project.
+#### Files
 
-* [x] Implement working cross platform AES encryption/decryption.
+You can encrypt/decrypt files.
-* [x] Different key sizes support.
+
-* [x] Improve performances.
+First, you need to initialize a `Cipher` object.
-* [x] Add exceptions.
+
-* [x] PBKDF2 support.
+```dart
-* [ ] Add other ciphers.
+final AES cipher = AES(
-* [ ] Clean platform specific code.
+    key: key,
-* [ ] Add asym crypto support...
+    mode: AESMode.gcm,
+    padding: AESPadding.none,
+);
+```
+
+Then, you can encrypt your file.
+
+```dart
+await cipher.encryptFile(plainText, cipherText);
+```
+
+> Note: `plainText` and `cipherText` are `File` objects.
+
+You can decrypt your file.
+
+```dart
+await cipher.decryptFile(cipherText, plainText);
+```
+
+#### Advanced
+
+You can force the use of a specific IV. Please note that the IV must be unique for each encryption.
+
+```dart
+final CipherText<AESCipherChunk> cipherText = await cipher.encryptWithIV(message, iv);
+```
+
+⚠️ Use `encrypt(...)` instead of `encryptWithIV(...)` if you don't know what you are doing.
