What is Code Signing?
Code signing is a security process that involves adding a digital signature to software code in order to validate its authenticity and integrity. This process provides assurance to end-users that the software they are installing is legitimate and has not been tampered with.
When a developer signs their code, they create a unique digital signature that is associated with their identity. This signature is then verified by a trusted third-party, known as a certificate authority, which issues a certificate to the developer.
The certificate contains the developer’s public key and other identifying information. When a user installs the signed software, their system verifies that the digital signature matches the developer’s public key, ensuring that the code has not been modified in any way since it was signed.
