Open the IE option and find the certificate we downloaded from the patent application website through "content"-"certificate". Select the certificate, and then click Export.
Click Next and select Yes, export the private key.
Format selection is personal information exchange, including all certificates in the certificate path if possible, and enabling certificate privacy.
Set an easy-to-remember password. Don't forget this time.
Click Browse to specify the export file name.
Find the export file and copy it to the directory "C: \ Program Files (x86) \ Kairende \ CA Certificate Control". Files with forgotten passwords can be deleted from this directory.
Close IE and reopen it, and you can log in to the electronic application network with the new certificate password. Congratulations.
