1. Download and install mobile phone signature software first.
2. Put your cer certificate file and key key in your mobile phone (for example, E:\ Other folders, you can put that folder anywhere, as long as you feel safe, the certificate will be lost or deleted by mistake! ), as shown in the figure, open and import your certificate and key, as well as unsigned software, as shown in the figure, and then click option-Sign, as shown in the figure. In addition, the software can save the path (key, cer), so it is more convenient to import the certificate and key next time. Click options > save configuration, so you don't need to enter a password and certificate next time you sign! The signature file is located in the same directory as the source file, and an "X" will be added to the file name. If it is # #. Sisx will become # #. After sisxx signed it.
3: If there is a password in the 3:key file, enter the password; If there is no password, please leave it blank. To use a key with a password, you should choose self-signing.
Tip: You must use the signing software, certificate and corresponding key in the certificate package to sign, otherwise you will get an error.
Because of the website format # #, I want to change my dropout to mp3, which you can download and change to zip. The certificate is uploaded in the form of a compressed package. Please correct it and decompress it with X Manager.
It is recommended to download with UC browser!
