Full Changelog: v0.5.0...v0.6.0

Version 0.5.0

• 🔐 Added AES-CCM (Counter with CBC-MAC, RFC-3610) support with AES(key).ccm(nonce), accepting a 7 to 13 byte nonce, additional authenticated data, and a configurable tag size.
• 🔤 Renamed AEAD extensions to fix a spelling error: ChaCha20ExtentionForPoly1305, XChaCha20ExtentionForPoly1305, Salsa20ExtentionForPoly1305, and XSalsa20ExtentionForPoly1305 are now ...ExtensionForPoly1305 (breaking change).
• 📝 Corrected the README features table by removing unavailable *Stream helper functions, and refreshed the embedded usage example.

Full Changelog: v0.4.0...v0.5.0

Version 0.4.0

• 🌊 Restored and redesigned stream processing support by refactoring cipher architecture around StreamCipher, AEADStreamCipher, and CipherPair.
• 🔐 Refactored AES modes, ChaCha20, Salsa20, XOR, and AEAD implementations to align behavior across one-shot and stream APIs.
• 🛠️ Updated nonce and typed-data internals plus AES cache generation logic for better correctness and maintainability.
• ✅ Expanded and updated test coverage across AES modes, stream ciphers, AEAD flows, integration parity, and core cipher behaviors.

Full Changelog: v0.3.0...v0.4.0

Version 0.3.0

What's Changed

• Removed Stream support (It will be available again in later versions).
• 🛡️ Strengthened input validation for AES-CBC by requiring IV length to be exactly 16 bytes.
• 🔒 Improved AEAD verification behavior in XChaCha20Poly1305 and XSalsa20Poly1305 by throwing StateError on authentication failure.
• ⚙️ Applied security hardening and reliability fixes across AES-GCM, ChaCha20/Salsa20 internals, cipher core helpers, and typed-data utilities.
• ✅ Expanded test coverage with additional security and validation tests, including AES-GCM and typed-data cases.
• 🧪 Added broader ChaCha20 and Salsa20 test vectors and scenarios.

New Contributors

• Change IV validation to require exactly 16 bytes for AES CBC mode by @elliotwutingfeng in #20
