Which keys are not stored in a virtual appliance for security?

In the context of security within a virtual appliance, it is essential to ensure that certain types of sensitive information are not stored in a retrievable manner, which could potentially lead to vulnerabilities.

SSH keys, while essential for secure communications and access, are typically generated and managed on the client side or through secure means rather than being stored within the virtual appliance itself. By not storing SSH keys in the appliance, it ensures that any unauthorized access to the virtual appliance does not compromise those keys, which are critical for maintaining secure shell access.

On the other hand, JWT signing keys, TLS certificates, and clear text passwords are more likely to be stored within the virtual appliance. JWT signing keys are utilized to ensure the authenticity of tokens, TLS certificates play a key role in encrypting communications, and while clear text passwords are considered insecure, they may still be stored in specific applications for functioning purposes.

Thus, the correct answer highlights the practice of not storing SSH keys in a virtual appliance to enhance its security posture, protecting critical access credentials from potential exposure.
