how can i prevent the time manipulation to the past? following scenario:
-license keys with time limit maybe 30 days
-offline check; the user must not have every time a internet connection(only once a week)
how can i prevent that the user reset his computer time to the past? the function TimeCheck() is in that case sense less, because it need a internet connection and the function …HasValidSignature(test.RSAPublicKey, 7)…. check only the future and ignore the past…that says my test.
