Architecture
------------

This project aims at the Storage of sensitive information such as passwords, username, and tokens.

**Current state and gaps**

Many services in ONAP use password based authentication. Eg: Database servers, publish/subscribe brokers etc.
Passwords are stored in plain text files in many services.
With multiple instances of these services, the attack surface area becomes very big.
Hence there is a need to ensure that attack surface related to password exposure is reduced.

**Requirement:**

Need for Secure Secret Management.
Services are expected to get the secret only on needed basis using secret reference and remove the secrets once they are used up.
