We do not have to tell you, Mr. or Ms. Developer, how crucial it is to protect your intellectual property and professional reputation. What we can tell you is how you can protect both through Comodo’s Code-Signing Certificate. Authenticating a code signer with a third party authenticator and tamper-proof “packaging” confirms the validity of the source and keeps the integrity of the content by confirming alterations or corruptions have not occurred once the code or software has been signed. Confidently leave your “mark” on the code you worked so hard to develop and protect your reputation by garnering trust from your customers by simply applying a code signing solution.

What exactly is Code Signing?

Code signing is widely used to protect software that is distributed over the Internet. Code signing does not alter it; it simply appends a digital signature to the executable code itself. When customers buy software in a store, the source of that software is obvious. Customers can tell who published the software, and they can see whether the package has been opened or not. These factors enable customers to make decisions about what software to purchase and how much to "trust" those products.

Customers who download digitally signed Active X controls, dynamic link libraries, .cab files or HTML content from your site can be confident that code really comes from you and has not been altered or corrupted since it was created and signed. Digital IDs serve as virtual "shrink-wrap" for your software: after you sign your code, if it is tampered with in any way, the digital signature will break and alert customers that the code has been altered and is not trustworthy.

What are the Features & Benefits of Code Signing Digital ID?

Customer Confidence

They protect and reassure your customers by assuring them that the integrity of the code they download from your site is intact - that it has not been tampered with or altered in transit.


After downloading, end users can be sure that the code they obtained really came from you, helping you preserve your business reputation and intellectual property. Digital ID's allow customers to identify the author of digitally signed code and contact them should an issue or query arise.

Seamless Integration with Industry-Standard Technology

Most browsers will not accept action commands from downloaded code unless the code is signed by a certificate from a trusted Certificate Authority, such as Comodo.

Ease of Use

Code signing certificates are easy to use in conjunction with the vendor software tools that developers use to create products, macro's and objects.
