Example input: 0200302007 (a hex value)



byte utf8 = "0200302007".getBytes("UTF-8");

MessageDigest messageDigest = MessageDigest.getInstance("SHA-1");

messageDigest.update(utf8);

return messageDigest.digest();


SHA1 expected result is: 129DB11A3DEAFDAD52BC7CBEB20FD7947F31B7B6



But the above code give results in:



ECC933969191424B4B67F3FA29C0E103471EC311


Why is that?

You need to specify the input value correctly:



byte utf8 = {0x2, 0x0, 0x30, 0x20, 0x7};

            Run scheduled task as local user group (not BUILTIN)

            Image
            0 I am trying to run a scheduled task with User Group (not a single user). This is working fine when I in the field "when running a task, use the following user account:" insert BUILTIN User Group (for example: Administrators or Users). But when I try it with the created Local User Group (example: TestGroup) it is not working. The Users in the TestGroup are the same as in the Administrators group. What could be the problem?
