AtlasLock V1 is a focused Windows utility that turns folders into encrypted
archives with a custom .atlas format. You pick a folder,
choose a password, and AtlasLock produces a single file you can move to
USB, keep as a private backup, or upload to cloud storage.
Under the hood it combines a hardened password-based key derivation step (Argon2) with modern authenticated encryption and fast Zstd compression. You get both privacy and smaller files without having to understand crypto settings or tweak a dozen options.
- Creates self-contained
.atlasfiles – no 3rd-party archiver required. - Password-based encryption with slow-to-guess key derivation (Argon2).
- Built-in unlock throttling to slow down repeated wrong password attempts.
