Code signing

Code signing certificate is a special SSL certificate encryption tool that can be used to protect your code and files during online transmission. It is not difficult to understand that people are reluctant to download and install any untrusted applications on their computers, which is why code signing certificates are so valuable. By using this encryption technology to sign a document, a third-party certification authority (CA) will confirm that you are the creator of the document, and if a third party makes any changes to the code, the certificate will automatically remind the user. In this way, you don't have to worry about someone changing your package without your authorization.

Code signing certificates are widely used throughout the industry. Microsoft, JavaSoft, Adobe and Apple all use this encryption and signature tool when releasing software. In addition, the code signing certificate can be used to sign almost any file format you can think of, including .exe, .ocx, .xpi, .msi, .dll, and .cab. If you need to transfer code online and want to make sure that no one makes any changes or uses your source code, a code signing certificate is basically necessary. It allows you to rest assured that once your software is published online, it will not be maliciously modified by other third parties, so consumers can rest assured. In addition, when they download and install your software, they don’t have to worry about being infected by malicious software and viruses.

Currently, there are not many Code Sign digital certificate manufacturers, including Digicert (including the original Symantec), Comodo, Entrust, etc. In terms of choice, generally large manufacturers will be willing to choose Digicert (the original Symantec brand), after all, the certificate is highly recognized. However, Comodo is also quite good in terms of cost performance. In fact, from the point of view of product safety, there is no difference between the two, but the degree of brand recognition is different. So for start-ups or companies that are not very large, consider Comodo.

In addition, when purchasing code signing, if your software is a driver or the like, you need to purchase an EV certificate for code signing.
