5.0.0 - 2025-09-05

• Application-ready time protocol: envelope, seal, replay protection, file chunking, public API.
• Pure Kaalka time-based logic, no external crypto.
• Envelope format: senderId, receiverId, timestamp, window, seq, ciphertext, seal.
• Time-based integrity (seal/MIC) and replay protection.
• File chunking for large file encryption/decryption.
• Flexible API: system UTC or user timestamp.
• Unit tests for envelope, replay, chunking, and time logic.
• Backward compatible with previous Kaalka features.

4.0.0 - 2025-07-22

Changed

• Robust extension handling and cross-language compatibility

Fixed

• All file/media types (images, binary, video, music, text, CSV, JSON, XML, etc.) are now encrypted/decrypted losslessly

Documentation

• README updated to reflect robust, lossless file/media support and cross-language compatibility
