“Military-grade encryption” is a marketing buzzword thrown around by many companies. But what does it actually mean, and how does it keep your files safe inside SecureVault?

What is AES-256?

AES stands for Advanced Encryption Standard. It is a symmetric block cipher chosen by the U.S. government to protect classified information. The “256” refers to the key size—256 bits.

To put that into perspective, a 256-bit key has $2^{256}$ possible combinations. That is a number so large that even if you used every computer on Earth to check billions of keys per second, it would still take longer than the age of the universe to crack a single file.

Zero-Knowledge Architecture

Encryption is only as strong as who holds the key. At SecureVault, we use a Zero-Knowledge architecture.

  • We don’t know your password.
  • We don’t see your files.
  • We cannot recover your account if you lose access.

Your password is processed locally on your device to decrypt your unique encryption key. This key never leaves your phone. This means that even if SecureVault’s servers were compromised (which wouldn’t matter since your files effectively live on your device), hackers would get nothing but scrambled noise.

Beyond Encryption: Disguises

Reviewing encryption is important, but physical privacy matters too. SecureVault allows you to disguise the app as a functioning Calculator or Clock.

If someone forces you to open the app, you can use a Decoy Vault. Entering a fake PIN opens a completely separate vault with harmless files, keeping your real private data safe without raising suspicion.

Security is about layers. Encryption is the foundation, but camouflage is the shield.
