Code Signing SSL Certificates are used for signing the installable code to authenticate the owner organisation name and create trust among users of software. These certificates are compatible with Windows, Adobe Air, Java, Firefox, Microsoft Office & VBA, Apple, Silverlight. If you install unsigned software on computer it shows warning message and People not download or install any applications that show warning popup on their computers, which is why code signing certificates are so valuable. By signing your installable file with this encryption technology, a third party Certification Authority (CA) will confirm you as the author of the file and the certificate will automatically alert the user if any changes are made to the code. That way you don’t have to worry that someone has altered your work without your knowledge.
