Cryptographic vault. Zero knowledge. Permanent.
There are words you cannot say today. Thoughts too early, too fragile, too dangerous. EterniCapsule lets you seal them in cryptographic metal—forever readable, forever unchangeable.
Write for yourself, a friend, or a stranger. Lock it with a passphrase only they know. When the time comes, they'll use their key to unlock what you left behind.
Pour your message into the form. No one reads it. No server stores the plaintext.
Encrypt it with a passphrase. The capsule glows as the fire hardens your words into permanent form.
Share the capsule ID. Only someone with the right key can read what's inside. Forever.
