This paper takes a ntokrnl.exe document as an example to introduce the signing process. This file is not a newly developed driver file, but I brought it after I installed the system. When the computer started, I was prompted that the file had no digital signature.

Download 64signer from the Internet first, and use "64signer" Baidu directly. After downloading, open the software, click "Open", load the file to be signed, or drag it directly to the software interface.

three

Then check "Turn on the TestSigning startup option", which will be checked by default. If it is not checked, it must be checked.

four

After completing the above two items, click the "Sign" button twice.

five

After the signature is successful, a prompt "ntoskrnl.exe has tested the authentication signature with 64 signers" will pop up, as shown below.

six

Then, when you close this window, if you change the TestSigning mode, you will get a prompt as shown in the figure below, and you must restart the computer before the application can take effect.

seven

Then open the properties of the ntokrnl file->; Digital signature->; Generally, you can see that the validity period has changed and the file can be used normally.

This program is mainly used by people who develop driver kernel programs. If the driver is installed for the hardware and the prompt file is not digitally signed, you can use the following link method.
