A customer reports that software the customer downloaded from a public website has malware in it. However, the company that created the software denies any malware in its software at delivery time. Which of the following techniques will address this concern?

Secure storage refers to the protection of data at rest, ensuring that sensitive information is stored safely to prevent unauthorized access. While it is important for protecting data, it does not directly address the issue of verifying the authenticity or integrity of software downloaded from a public website.

Static code analysis involves examining source code for vulnerabilities without executing it. While this can help in identifying potential security flaws within the software, it does not provide a mechanism for users to confirm that the software they have downloaded has not been altered or contains malware after it was distributed.

Input validation is a technique used to ensure that data provided to a program is correct and secure before processing it. Although crucial for preventing certain types of attacks, it does not pertain to the verification of the software's integrity or the assurance that it is free from malware when downloaded.
