When a company develops and distributes a program, it may distribute a program that includes a malignant code or virus. However, a user who downloads a program has no way of checking if the downloaded program contains a virus that can damage the computer, or if it has a malignant code that can leak important information.
						As such, when a digital signature is added using a CODESIGN certificate to a distributed program, the distributing company’s information is displayed to the user via a security alert window when he/she downloads the program. This allows the user to confirm the credibility and safety of the program, which helps the user to download and install the program with confidence.
A program signed using a CODESIGN certificate guarantees the fact that the corresponding program was not altered illegally, and was distributed safely by a trusted company.
2. Reinforce confidence in the companyUsers can confirm the exact name of the company distributing the program, therefore it improves customer confidence in the company.
