AES-256 encryption explained for photo vaults

AES-256 is a strong cipher. For vault apps, insist on authenticated encryption (like GCM), keys derived on device, and a story that matches the privacy label—not just the words “AES-256” on a screenshot.

Cipher vs lock screen

A PIN in front of unencrypted JPEGs is not AES. AES transforms file bytes so copied storage is ciphertext without the key.

Why GCM shows up

GCM adds authentication so tampered ciphertext fails to decrypt cleanly. Blopman uses AES-256-GCM on imported files.

What encryption does not solve

FAQ

Is AES-256 enough by itself?

It is necessary but not sufficient. Key handling, recovery, accounts, and leftover copies decide real-world privacy.
