Code signing certificate is a software developer or individual developer who digitally signs his software so that users can download it to mobile terminals safely on the Internet. Code signing certificate enables developers to add digital signatures to their code, so that users can determine the real identity of code developers when downloading, and the code has not been illegally tampered with or destroyed during transmission.

Simply put, it is to attach a certificate to your own software to ensure that the software will not be tampered with and destroyed during circulation. Mainly to prevent malicious third parties from inserting advertisements or Trojans into your software.

Digital signature certificates are issued by authoritative and credible certification authorities, and Microsoft has recommended five certification authorities in official website. WoSign is the only recommended institution in China to buy code signing certificate.
