With code signing, consumers may feel confident about the software they are downloading and can stop worrying about infecting their computer or mobile device with malware. Code signing has grown in importance for software developers and distributors as more software may be downloaded from the Internet.
Malware can be easily installed on a victim's computer by an attacker who poses as a trustworthy source. As long as users only download software that is regarded as safe by their operating system, code signing ensures that these types of assaults cannot happen.
Nowadays, the Operating System looks for the digital certificate produced through code signing when software is downloaded onto a computer to ensure the security of the software being installed. The user is informed and given the option to stop or continue the installation if no digital certificate is detected.
