EternaKeys is a zero-knowledge digital legacy vault. AES-256-GCM encryption ensures your memories, assets, and final wishes are passed seamlessly to loved ones—not lost to the digital void.
Families spend an average of $12,000+ settling a loved one's affairs without access to digital accounts and assets.
You decide who receives what, and when. EternaKeys executes your intentions with precision — no middlemen, no ambiguity.
Billions in crypto and banking assets are lost annually because passwords and keys become inaccessible when their owners pass.
Your vault is encrypted before it ever reaches our servers. We store only ciphertext and operational metadata necessary for the service. Without your passphrase, vault contents are indecipherable — by design, not by policy.
At the most critical time.
Your vault is encrypted on your device before any data is transmitted. The key derives entirely from your passphrase and never leaves your browser. What reaches our servers is indecipherable without it.

↓ HKDF-SHA256 (domain separation)
encKey ← AES-256-GCM
searchKey ← HMAC blind index

Our Commitment to You
Your vault contents are encrypted with a key that derives from your passphrase alone. EternaKeys never receives it, stores it, or has access to it — by architectural design, not by promise.
Your data is encrypted on your device before transmission. Our servers never receive plaintext.
We store only ciphertext and operational metadata (item types, sizes, timestamps) necessary for the service. Without your passphrase, vault contents are indecipherable.
Not for our analytics, our access, or any third-party interest. Built entirely to serve your family.
EternaKeys is continuously refined to provide greater protection, clearer guidance, and more dependable security — for as long as your family depends on it.
EternaKeys stores your most important information — encrypted, organized, and ready for the people who will need it most.
