Updating Zencrypt Databases

Updating Zencrypt Databases:

• Store keys and user information in a SQL or NoSQL database (MySQL, SQLite, MongoDB, PostgreSQL, etc.)

• Integrate key expiry and key rotation logs in a secure database table

• Implement user authentication and roles for key usage (which ties directly into data defense)

• Possibly demonstrate how to store encrypted data objects within the database and decrypt on retrieval

With this final release of Zencrypt v5 I am planning on integrating database functionality for storing keys, user credentials, logs, analytics, and even encrypted data. This diagram focuses specifically on the database enhancement portion of Zencrypt and shows the major steps for connecting, authenticating, and performing database operations securely.
