Your password alone
isn't enough anymore

Parcela splits encrypted files into shares. Attackers need both your password and physical access to your shares.

Traditional encryption has one weakness

Steal the password, steal the data. Parcela eliminates this.

🔓

Password stolen

Phishing, keylogger, breach

Traditional❌ Compromised
Parcela✓ Still safe
💻

Files stolen

Laptop theft, cloud hack

Traditional❌ Brute-force
Parcela✓ Useless alone
📦

One share stolen

Partial data obtained

Traditional— N/A
Parcela✓ Need 2 of 3

How it works

1

Encrypt

AES-256-GCM with your password

2

Split

Divide into 3 shares

3

Distribute

USB, cloud, safe deposit

4

Recover

Any 2 shares + password

Features

🔐

2-of-3 Secret Sharing

Any 2 shares reconstruct the file. Lose one and you're still fine.

🛡️

AES-256-GCM + Argon2

Authenticated encryption with memory-hard key derivation.

🖼️

Steganographic Shares

Shares embedded in PNG images via custom chunks. Look like normal files.

✅

Security Verification

Run attack simulations to verify cryptographic properties.

💾

Virtual Drive

RAM-backed filesystem. Decrypted files stay in memory.

⌨️

GUI + CLI

Desktop app for all platforms. CLI for scripting.

🖼️ Shares Hidden in Images

Parcela embeds your encrypted shares inside ordinary PNG images. They open normally in any image viewer.

  • 20 different icon designs to choose from
  • Data stored in custom PNG chunks (not pixels)
  • Shares look like normal image files
  • Note: avoid re-saving or uploading to services that re-encode images
Shares stored as PNG images

✅ Verify Security with Attack Simulations

Don't just trust — verify. Parcela can run real attack simulations against your vault to confirm cryptographic properties.

  • Tests single-share recovery attacks
  • Simulates bit-flip tampering on ciphertext
  • Checks nonce uniqueness (no reuse vulnerabilities)
  • Verifies share randomness with chi-square analysis
  • Confirms 2-of-3 threshold property holds
