SSL is often used in authentication, data encryption, and other applications. To use SSL, we have our own password certificate. Digital Certificates are generally applied to professional certification companies (such as VeriSign) and are charged. In some cases, we just want to use encrypted data communication instead of authentication, you can create a certificate by you

From the above, we can see that csrutil mainly modifies the sip settings by setting the value in IODeviceTree:/options, and uses the ioreg tool to check the value in IODeviceTree:/options. The command line is as follows: ioreg-l-p IODeviceTree. If the SIP is not disabled, the result is as follows:
