Encrypted File & Text Locker
AES-256-GCMSend files & text securely between devices. Encrypted with military-grade AES-256-GCM in your browser before transmission.
1. Encrypt & Package
Select a file or enter secret text to generate a self-decrypting encrypted package or copy payload.
2. Decrypt Package
Decrypt an encrypted `.e2e` file or paste encrypted raw payload directly in your browser.
Zero-Knowledge Cryptographic Architecture
This tool implements client-side PBKDF2 key derivation (100,000 iterations of SHA-256) with a cryptographic salt, coupled with AES-256-GCM authenticated encryption. Even if intercepted in transit, ciphertext cannot be forged or decrypted without the shared passphrase.
100% Local & In-Browser Execution
Your device powers this tool. Zero cloud uploads.
All file processing, calculations, and conversions run entirely inside your browser using your device's CPU and memory. Your data never touches any external server.
Processing speed depends on your device's hardware. Handling heavy media or large documents may temporarily utilize local RAM and processor capacity.
