A Dart project under LGPL-3.0 license.

CryptDart

Unified cryptography library for Dart. Provides easy-to-use interfaces for symmetric/asymmetric encryption, digital signatures, and key management. Built on PointyCastle and BasicUtils.

Features

• Symmetric encryption: AES, TripleDES, ChaCha20
• Asymmetric encryption: RSA
• Digital signatures: HMAC, RSA signature
• Key generation and management
• Expiration logic for keys and ciphers
• Centralized utilities for encoding, random generation, and PEM parsing

Installation

Add to your pubspec.yaml:

dependencies:
	cryptdart: ^1.0.0

Run:

dart pub get

Usage Example

import 'package:cryptdart/cryptdart.dart';

void main() async {
	// Generate AES key
	final aesKey = AESCipher.generateKey();
	final cipher = AESCipher((parent: (key: aesKey)));
	final encrypted = cipher.encrypt([1, 2, 3, 4]);
	final decrypted = cipher.decrypt(encrypted);

	// Generate RSA key pair
	final rsaKeys = await RSACipher.generateKeyPair();
	final rsaCipher = RSACipher((parent: (publicKey: rsaKeys['publicKey']!, privateKey: rsaKeys['privateKey']!)));
	final rsaEncrypted = rsaCipher.encrypt([1, 2, 3, 4]);
	final rsaDecrypted = rsaCipher.decrypt(rsaEncrypted);
}
