Introducing CryptGuard — an advanced encryption solution that puts security and usability at the forefront. Whether you’re handling sensitive files, creating hidden volumes for plausible deniability, or simply looking for a trusted way to protect your data, CryptGuard offers:

- Strong Encryption
  Powered by ChaCha20-Poly1305, ensuring both confidentiality and integrity in one go.

- Robust Key Derivation
  Uses Argon2id to safeguard against brute-force attempts, automatically adjusting memory usage if resources are limited.

- Hidden Volumes
  Create a decoy volume alongside a real, protected one; each with separate passwords, plus an ephemeral token for the real data.

- Large-File Support
  Stream data in chunks, reducing memory spikes and making it seamless to encrypt or decrypt huge files.

- Atomic Metadata
  Prevents corruption by writing metadata safely, so no partial writes leave your data inaccessible.

- Effortless Distribution
  Available as a single `.exe` file — no extra dependencies needed on Windows.

Why CryptGuard?
- Security best practices baked in.  
- Thorough error handling, ensuring incomplete files and leftover sensitive keys won’t persist.  
- Actively maintained, with an open invitation for community feedback and contributions.
