Getting todays date in HISE

[dejans]

@Lunacy-Audio @ustk Yep, I'm also using this approach but only to encrypt the registration details file. This can be easily decrypted when the machine id generator code is found/cracked. But the interesting and creative part is that you can hide, let's say some kind of token in the license.dat. It can be a single character at a certain place in the serial, for example. Then at certain points, or based on user activity you do checks for that token (f.e. when a user moves a filter cutoff, you check if lfo is active && the plugin is running at least for 2 hours && token is not valid, then trigger a notification, mute the output, delete the license.dat or do whatever... The point is to make a couple of these checks that happen sparsely. Eventually, it'll be cracked, but hopefully, you can delay the crack long enough to convert a number of pirate users to legitimate ones...

That's interesting for sure. I'll need to dive deeper into that and add some more checks. Thanks!

[ustk]

@Lunacy-Audio I have approximately the same process added with a limited number of activations/machines, machine ID, and strong encryption to generate a license file.
About the time check, I can try to add an API...

[Casey Kolb]

@ustk Would be appreciated!

[LeeC]

@ustk yeah that would be ace... Much appreciated!

Guys, does having the number of days since 1970 fit your needs?

Do you prefer the system date? or anything?

In what format? days, hours, sec, ms, string date...

or an object with everything but I don't know if I am able to do that..

[Casey Kolb]

@ustk I think just being able to grab the current system date and time is super useful. Maybe something like Engine.getSystemDate() returns

{
  year: 2020,
  month: 11,
  day: 19,
  hour: 14,
  minute: 55,
  second: 32
}

But I'm sure there's a better way of returning it. This isn't my forte haha.

I would suggest to not go down the rabbit hole of trying to outsmart a imaginary cracker. Just make sure your plugin can‘t be copied to multiple machines by a simple user and leave the rest to companies who sell usb dongles for a living...

[ustk]

@Lunacy-Audio The juce Time class allows everything we need so it is just a matter of what we need and I'll find a way to make the API
Currently, I've made one that gives the number of days since 1970. I've just made a simple conversion since it is originally in milliseconds...

[Casey Kolb]

Sounds reasonable

[ustk]

@Lunacy-Audio What sounds reasonable?

[Casey Kolb]

The number of days since 1970. Also, the addition of the function I mentioned above would be great too, but no rush.

[LeeC]

@ustk The time since 1970 and also any format of system date would be great for now.
If it's too tricky to pull back an object with the attributes that @Lunacy-Audio suggested then a simple string would be useful too.

Appreciate you looking into this for us
I'm sure it will come in handy for other HISE things outside of copy protection also.

[ustk]

Ok guys I've added the Engine.getSystemTime(bool includeDividerCharacters) API from Juce
it returns a fully described string of the date and time in ISO-8601 format (using the local timezone) with or without divider characters.
It is up to you @Christoph-Hart to merge it of course, but if you find it unnecessary, the mod is easy for anyone interested...

// Returns a string with separator:
2020-11-21T16:07:08.525+01:00

// Or without separator
20201121T160708.525+0100

@ustk Thank You!

[LeeC]

@ustk Legend thanks!

[Casey Kolb]

@ustk Woo! Thanks man.

[LeeC]

@Christoph-Hart is it possible to get this merged?
Cheers

[LeeC]

@d-healey are you still maintaining a branch that we could potentially merge this change made by @ustk to?
Desperate to make use of this 'Date Logic' but don't want to pester the man (@Christoph-Hart) anymore than we need to.

Cheers

[Christoph Hart]

It‘s already merged in the main scriptnode branch.
