Release-Keys and Test-Keys detection

컴파일 중 커널 서명 키 확인

Release-Keys and Test-Keys have to do with how the kernel is signed when it is compiled.

Release-Keys means it was signed with an official Key from an official developer.

Test-Keys means it was signed with a custom key generated by a third-party developer. From a security standpoint, Release-Keys generally means the kernel is more secure, which is not always the case.
