Secure File Transfer Portal using AES-256 Encryption
Zero-knowledge client-side encryption directly inside your browser. Your data is encrypted before it ever leaves your device.
Your file, encrypted before it leaves your browser.
How It Works
Encrypt in browser
A 256-bit AES key is derived from your password using PBKDF2 (100,000 iterations). Your file and an integrity hash are encrypted locally via the Web Crypto API.
Upload encrypted data only
Only the encrypted ciphertext, salt, and IV are transmitted to the server. Neither your plaintext file nor your password ever touches the network unencrypted.
Decrypt with password
The recipient enters the password to decrypt the file in their browser. The server automatically removes the encrypted payload immediately after download.
