Secure Credential Vault

Description

Implement a secure credential vault for storing API keys and other secrets for cloud services. This will allow users to safely connect their Spacedrive library to their cloud storage accounts.

Implementation Steps

1. Design the database schema for the credential vault, ensuring that all secrets are encrypted at rest.
2. Implement the logic for adding, updating, and deleting credentials.
3. Use the operating system's keychain or other secure storage mechanism to protect the master encryption key for the vault.
4. Integrate the credential vault with the cloud volume system.

Acceptance Criteria

• Credentials are encrypted at rest in the database.
• The master encryption key is stored securely.
• The system can retrieve credentials to authenticate with cloud services.
