A certificate can sign all the programs that need to be signed, and the signed programs can only be used on the IMEI machine included in the certificate.
A PID certificate can contain at most 1000 IMEI, so a certificate can be used for at most 1000 imei * * * *.
PID certificate has 17 authority, which is higher than the original ordinary personal certificate's 13 authority.
Not all programs need to be signed by themselves, and there will be instructions when the program is released. If you don't explain it, install it first, and then sign it yourself when you encounter the prompt of "certificate error"
The certificate is valid for 3 years. After the certificate expires, you can still sign it, but you need to adjust the date of the mobile phone when installing it.
You need a key to make a certificate, and you need the same key to sign with this certificate, otherwise you can't sign.
The signing tool recommended by this forum has the built-in key of this forum, which can directly sign the certificate applied by this forum.
