What is Code Signing?

Code signing is the process of attaching a digital signature to application binaries. Cryptographic functions are used to identify a specific application binary and associate that binary with a specific developer or organization. This allows other systems to understand several things about an application:

  • The source of the application based on who signed the application binary; and
  • Whether the application binary has been changed since it was originally signed.
