Chapose is a modern, high-performance file encryption CLI based on ChaCha20-Poly1305 (AEAD), designed for strong confidentiality and integrity verification in real-world workflows. It uses a streaming architecture to process very large files with low memory overhead, avoids loading full plaintext into memory, and provides clear failure signals on authentication mismatch. Chapose supports password- and keyfile-based operation, plus seamless environment-variable driven usage for automation.
