What is a CODESIGN Certificate?

HOME > CODESIGN Certificate > What is a CODESIGN Certificate?
CODESIGN refers to a digital signature authenticated by a certified authenticating organization that proves a program can be trusted and is safe. It is used when a user attempts to install programs that provide extra features (ActiveX, JAVA Applet, etc.) on his/her computer.

Have you ever seen a yellow ActiveX warning message appear at the top/bottom of your browser while you were surfing the internet?
These warning messages appear when Windows blocks a particular file from being downloading because it cannot confirm the publisher of the program, or (using banking as an example) when the system alerts the user regarding files to be installed when he/she tries to log-in to a website and execute financial transactions.


The necessity and benefits of a CODESIGN certificate

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.

1. Secure integrity of the program

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 company

Users can confirm the exact name of the company distributing the program, therefore it improves customer confidence in the company.

1. What happens if I do not use the application program certificate?

Android, iPhone and Windows Mobile platforms are supported. However, Windows Kernel-Mode is not supported. If you require Kernel-Mode for your program, please call the customer center and receive detailed instructions.
5. Can I use a different name for the publisher?
The application certificate requires a corporate authentication process. Therefore you are required to use the company name (publisher name) that appears on your business license.
6. Can I use a Korean publisher name?
No, you are required to use the full English name of your company. (Company name that matches the company name printed on your business license, or company name printed on your English business license)

You will go through a phone authentication process 2 days after your apply is received by the company. Once authentication is complete, you will receive your certificate within 1 hour.
