How it works
Your password is stretched through 100,000 iterations of PBKDF2-SHA256 with a random salt to derive a 256-bit key.
The file is encrypted with AES-256-GCM using a random IV. The auth tag ensures any tampering is detected on decrypt.
Salt and IV are stored in the .enc file header. You only need your password to decrypt it — on any device with this page.
