lazychacha #
Lazy ChaCha20-Poly1305 in Flutter base on cryptography
Algorithm details #
- Key exchange: X25519
- Encryption: ChaCha20
- Authentication: Poly1305
Usage #
- pubspec.yml
dependencies:
lazychacha: ^1.0.0
- Dart
final lazychacha = LazyChaCha.instance;
How to use #
- Generate KeyPair
final keyPair = await KeyPair.newKeyPair();
- Key Exchange & Shared Key
final clientKeyPair = await KeyPair.newKeyPair();
final serverKeyPair = await KeyPair.newKeyPair();
final clientSharedKey = await clientKeyPair.sharedKey(serverKeyPair.pk);
- Encrypt
final lazyChaCha = LazyChaCha.instance;
final sharedKey = await clientKeyPair.sharedKey(serverKeyPair.pk);
const plaintext = '{"message": "Hi"}';
final ciphertext = await lazyChaCha.encrypt(plaintext, sharedKey);
- Decrypt
final lazyChaCha = LazyChaCha.instance;
final sharedKey = await clientKeyPair.sharedKey(serverKeyPair.pk);
const ciphertext = '1ec54672d8ef2cca351';
final plaintext = await lazyChaCha.decrypt(ciphertext, sharedKey);
