Code Signing Certificates
To prevent tampering or compromise of applications by unauthorized parties, software developers digitally sign their programs with code signing certificates.
These digital certificates are especially useful in applications that are distributed through the Internet, where applications can pass through a number of suspicious parties or websites before it finally gets downloaded and installed.
Unsigned applications can easily be altered to include malware or viruses, and these untrusted applications will display warning messages resulting in lower installation yields. A code signing certificate issued from a trusted Certificate Authority such as SSL.com can prevent all of those problems.
