BiuCrypt.
A PyQt6 file-encryption suite for securely processing files and folders with Argon2id, AES-256-GCM, and ChaCha20-Poly1305.
OVERVIEW
Protection with clear boundaries.
BiuCrypt is a practical desktop suite for encrypting and decrypting files or folders. Its format validates headers, derives protection from the user’s password, processes data in chunks, and keeps the workflow explicit and controlled.
PROJECT SCOPE
Security in the workflow.
Modern key derivation
Argon2id derives protection from the chosen password before encryption begins.
Authenticated encryption
AES-256-GCM and ChaCha20-Poly1305 protect encrypted content with integrity-aware processing.
File & folder flow
Files and folders are handled with progress, cancellation, safe extraction checks, and optional secure cleanup.
Focus: Making strong file protection approachable without hiding the security decisions that matter.
