What documents in your iCloud Drive would actually matter if decrypted in 2030?

A thought experiment that kept me up while building Qpher Vault.

Most of what's in iCloud Drive in 2026 won't matter in 2030. A grocery list. A meme. A receipt for socks.

But some of it will:

• A passport scan still works in 2030

• A signed contract still binds you

• A 2026 tax return still ties to your name and SSN

• A custody agreement, an NDA, a board resolution

These have shelf lives measured in decades, not days.

Right now, nation-state attackers are storing every encrypted file they can grab — TLS traffic, backup blobs, intercepted attachments. Not to decrypt today. To decrypt in 2030, when quantum computers can break RSA and ECC.

The strategy has a name: harvest now, decrypt later.

So I'm curious — when you scroll through your iCloud Drive right now, which 3–5 files would you actually NOT want in someone else's hands six years from now?

(Building Qpher Vault to be exactly that pocket. Launching here tomorrow.)
