Database ERD

Encryption System

Every user has a private and a public key which derived from the user's password and a salt. Public keys are uploaded to the server where other users can retrieve.

Every vault has a vault key which is used to encrypt and decrypt the vault items. Vault keys are stored in encrypted form in the database. Vault keys need to be decrypted before use. Decryption is done on the client side as well.

To understand how encryption and decryption work in the application, you can study below graphs and flows. They only includes parts related to encryption/decryption (permission management, audit logging, error handling, etc. are not included).
