CodeSigningZertifikat

CodeSigningZertifikat is a digital certificate used to digitally sign executable code, such as software applications, drivers, and scripts. The primary purpose of a CodeSigningZertifikat is to establish the identity of the software publisher and to ensure that the code has not been tampered with since it was signed.

When a developer signs their code with a CodeSigningZertifikat, they are essentially providing a guarantee to end-users. This guarantee has two main components. First, it authenticates the publisher, assuring users that the software comes from a known and trusted source. This helps to prevent malicious actors from distributing malware under a false identity. Second, it ensures code integrity. Any modification to the signed code, even a minor one, will invalidate the digital signature, alerting the user that the software may be compromised.

CodeSigningZertifikate are issued by trusted Certificate Authorities (CAs) after a rigorous verification process of the applicant's identity and legitimacy. This process is crucial for maintaining the trustworthiness of the system. Operating systems and web browsers often use these signatures to make decisions about whether to trust and execute software. For example, Windows SmartScreen or macOS Gatekeeper rely on code signing to warn users about potentially untrusted applications.

In summary, a CodeSigningZertifikat is a vital security tool in the software development and distribution ecosystem, fostering trust between developers and users by verifying the origin and integrity of digital content.
