Vault

Context you own. Encrypted where it lives.

Slices are encrypted in this browser with a key derived from your passphrase (PBKDF2, 310k rounds → AES-256-GCM). Prism stores ciphertext and a manifest, never the key. Each slice carries the highest beam allowed to read it.

Passphrase

Never sent anywhere. Forget it and the vault is gone.

Slices0

Unlock to list slices.

Vault locked

Enter your passphrase. On first use, this creates a new vault in this browser with a couple of example slices.

Share a slice

Generates a one-time link containing a fresh key for just this slice, with an expiry. The recipient's browser decrypts it; Prism only relays ciphertext.
