Encrypt a crypto wallet seed phrase — a digital, sealed backup
The safest backup of a crypto seed phrase is a metal plate in a safe. The second-safest is a sealed file on a machine that does not phone home. Elba gives you the second option, at rest, with AES-256-GCM.
When digital makes sense
As a redundant backup to the metal, or for smaller ‘hot’ wallets, a sealed Elba vault beats a text file, a screenshot, or a note in a password manager whose vendor could be breached.
A safer routine
Write the seed inside the vault. Seal it. Copy the sealed file to two USB sticks kept in different physical locations. Never type the seed on a networked machine again.
Questions people actually ask
- Is this better than the wallet's own backup?
- It's a different kind of backup — offline, portable, and outside the wallet vendor's ecosystem.
- What if I forget the Elba password too?
- Then the digital backup is dead. That's why the physical backup exists.
