Need to calculate CRC or MD5 of a texture

[linuxgurugamer]

I've been trying to figure out how to get a CRC or MD5 of a texture.  I need this because I'm working on a mod to hide toolbar buttons, and the only unique data which is consistent between buttons is the texture.  There isn't anything else I can find which will uniquely identify a button.  But I can't figure out how to do this, the RawImage which is stored in the sprite seems to be hidden so deep I can't find it.

any ideas?

This id needs to be consistent between different game runs, so I can't use the object hash, since that changes every game run

As for getting the texture: does applicationLauncherButton.toggleButton.Image.mainTexture work? You might have to make the texture readable, before you can work with it: https://github.com/Kopernicus/Kopernicus/blob/master/Kopernicus/Kopernicus/Utility.cs#L1058-L1082

As for calculating the hash: You could export the texture into a JPEG or PNG formatted byte array, and calculate the hash from that.
