AES Crypt Enthusiasts,

We are excited to announce the release of AES Crypt 4 , the fourth major version of our popular encryption software. AES Crypt 4 is available as a GUI and command-line application for Windows, Linux, and Mac, with both binaries and source code published.

Key Updates: Enhanced Security: The key derivation function now uses FIPS-recommended HMAC-SHA-512 with 300,000 iterations, configurable via the command-line tool. We’ve also switched to PKCS#7 padding. Performance Boost: Intel Intrinsics functions improve performance by approximately 30% on Intel processors. Apple Silicon Support: The Mac version is now compiled for Apple Silicon. Safety Measures: Mac and Linux versions now refuse to overwrite existing files, aligning with the Windows version. Command-Line Enhancements: More options, integrated key generation, and a progress meter for long files. Code Overhaul: Rewritten in C++20 with daily unit tests and improved integration tests for enhanced code safety. Backward Compatibility: AES Crypt 4 remains fully compatible with all previous versions, ensuring access to encrypted files created by older versions. All packages are available on https://www.aescrypt.com.

Cheer! Paul
