If you use Dropbox, Google Drive, or OneDrive, you cannot guarantee the privacy of your data. Encrypting your files with Picocrypt before uploading them ensures zero-knowledge privacy—even if the cloud provider suffers a catastrophic data breach, your files remain unreadable.

To thwart brute-force and hardware-accelerated dictionary attacks, Picocrypt utilizes Argon2id, the winner of the Password Hashing Competition. Argon2id is memory-hard, making it highly resistant to cracking attempts powered by specialized Graphics Processing Units (GPUs) or Application-Specific Integrated Circuits (ASICs). 2. Primary Encryption: XChaCha20

The developer is actively working on features that will cement Picocrypt as the "standard" for file encryption: Picocrypt is built to withstand modern threats

Unlike enterprise tools like BitLocker or VeraCrypt, Picocrypt doesn't try to encrypt your whole hard drive. It focuses on that is so simple a non-technical user can drag and drop a file, set a password, and be done in seconds.
