Kaalka Encryption Algorithm for Dart

Robust, timestamp-based encryption for Dart, compatible with Python and JavaScript implementations. Uses angles and trigonometric functions derived from timestamps for strong, time-dependent encryption.

Features

• Robust encryption using timestamp-based keys (angles, trigonometric functions)
• Cross-platform: Compatible with Python and Node.js Kaalka implementations
• Flexible API: Use system time, NTP, or custom timestamp for encryption/decryption
• Packet support: Example wrapper for secure message packets

Installation

Add to your pubspec.yaml:

dependencies:
  kaalka:
    git:
      url: https://github.com/PIYUSH-MISHRA-00/Kaalka-Encryption-Algorithm.git

Usage

Basic Encryption/Decryption

import 'package:kaalka/kaalka.dart';

void main() {
  final kaalka = Kaalka(); // Uses current system time
  final message = 'Hello, Kaalka!';
  final encrypted = kaalka.encrypt(message); // Encrypt with current time
  final decrypted = kaalka.decrypt(encrypted); // Decrypt with same time
  print('Encrypted: $encrypted');
  print('Decrypted: $decrypted');
}

Using a Custom Timestamp

import 'package:kaalka/kaalka.dart';

final kaalka = Kaalka('10:15:30'); // HH:MM:SS, MM:SS, or SS
final encrypted = kaalka.encrypt('Secret', '10:15:30');
final decrypted = kaalka.decrypt(encrypted, '10:15:30');

Using KaalkaNTP (NTP time, async)

import 'package:kaalka/kaalka_ntp.dart';

void main() async {
  final encrypted = await KaalkaNTP.encryptWithNtp('Hello!');
  final decrypted = await KaalkaNTP.decryptWithNtp(encrypted);
  print('Encrypted: $encrypted');
  print('Decrypted: $decrypted');
}

Packet Example

import 'package:kaalka/packet.dart';

final packet = Packet('Payload', timeKey: '12:34:56');
packet.encrypt();
final decrypted = packet.decrypt();

API Reference

Kaalka

• Kaalka([dynamic timeKey]) — Create instance with optional timestamp
• String encrypt(String data, [dynamic timeKey]) — Encrypt data
• String decrypt(String encrypted, [dynamic timeKey]) — Decrypt data

KaalkaNTP

• static Future<String> encryptWithNtp(String data, {dynamic timeKey})
• static Future<String> decryptWithNtp(String data, {dynamic timeKey})

Packet

• Packet(String data, {dynamic timeKey})
• void encrypt()
• String decrypt()

Timestamp Format

• Accepts int (seconds), String (HH:MM:SS, MM:SS, or SS)
• If omitted, uses current system time

Compatibility

• Compatible with Python and Node.js Kaalka libraries
