Code Signing Certificates is the course in which digital certificates are use to sign software applications for safe delivery.
A digitally signed software with a certificate issued by a reputable public certificate authority allows developers to assure their users that the software they want to install was develope by a well-known and trusted developer.
Code signing is beneficial for software distributed on the Internet, where there are many possibilities to modify malicious third-party applications to apply malware or viruses or legitimate software vendors.
By digitally signing the code, developers can also prevent users from clicking on operating system warning messages or changing default security settings during software installation.

Why should I Sign my Code?
Customers who will install the software need security – they wanted to know who the software developer is and whether the software they are installing is safe or not. The signature code allows users to feel completely comfortable when using their software online.
When does the Code Signing Certificate Expire?
Code signing certificates are valid for a period of one to three years. You can sign all required applications with a code-signing certificate, as long as the application is disperse by the organization for which the certificate was the issue.
The main challenge with it is to safeguard the private signing key attached to the signing certificate. The certificate loses its reliability if a permit is compromised, jeopardizing the program it has already signed.
Follow these code-signing best practices:
- Reduce access to private keys.
- Limit the number of connections to computers that have keys.
- Limit the number of users who have password access.
- To minimize access to keys, use physical security controls.
The timestamp allows you to authenticate the code after the certificate is revoke. Time-stamped certificates can be an issue for up to 11 years.
Code verification is require before signing or issuing any code. To prevent unauthorized or malicious code signing, following a signing submission and approval process. To review or respond to incidents, record all of your practices.
Virus scan code before signing.
Code signing does not guarantee code protection; it ensures the editor whether the code has been an update or not. Be careful when integrating code from other sources. To improve the issued code standard, apply virus scanning.
Learn the distinction between proof signing and authorization signing.
Proof of signing private keys and certificates results in fewer security checks on access than signing certificates and private keys. Test signing certificates can be self-sign or emerge through an internal test CA.
Test certificates must link to a root certificate that is entirely independent of the root certificate used to sign publicly published products; this measure ensures that test certificates are only trust in the intended test environment.
To test and sign pre-release versions of the software, set up a separate test signature infrastructure.
