Signing with a certificate is mainly for security!
Many people have also asked me: where should I put the certificate? Put it in your cell phone?
In fact, the certificate will only be used when you need to sign it, so you must keep it well and put it anywhere, such as computer, USB flash drive and so on. As long as it can be preserved, it can be found when it is used.
The certificate is not an application software, so you don't need to put it in your mobile phone. If there is really no place to save it, you can use your mobile phone as a USB flash drive to save the certificate.
If you still don't understand anything, you can send me a message!
