Vault items are the records you want beneficiaries to recover later. They can be text records, passwords, notes, crypto keys, documents, or files.
Encryption path
Eternum encrypts vault content in your browser before upload.
Derive the master key
Your browser derives a master key from your PIN or password with Argon2id.
Generate an item key
Each item gets its own data encryption key.
Encrypt content
The item content is encrypted with AES-GCM. The server receives ciphertext only.
Store metadata and blob data
Metadata is stored in PostgreSQL. Encrypted file blobs are stored in object storage.
Item limits by plan
| Plan | Vault items |
|---|
| Seed | 3 |
| Legacy | Unlimited |
| Estate | Unlimited |
Do not store the only copy of your credential in the vault. You need the credential to decrypt the vault before recovery.
