What is the main function of a hardware key manager in security?

The primary function of a hardware key manager in security is to serve as a secure repository for sensitive information, particularly cryptographic keys and credentials such as passwords. By utilizing specialized hardware to safeguard these keys, a hardware key manager ensures that the sensitive information remains protected from unauthorized access and potential breaches. This dedicated approach to managing keys is crucial because cryptographic keys are essential for encrypting and decrypting data, thus playing a central role in maintaining data confidentiality and integrity.

While creating user accounts, providing access control mechanisms, and managing network security protocols are important aspects of a security infrastructure, they are typically not the core functions of a hardware key manager. The focused capability of a hardware key manager to securely handle cryptographic material sets it apart as a vital component in safeguarding security measures.
