Alright, the reason I am asking is I am analyzing a software and they have used a certain type of key. I know I have seen such keys before so there must be a standard.
It looks like this:
ED19769F-D53C-49BB-B23F-CB67DF1A69B
I know this is a simple question but it is difficulty to formulate a google search string for this problem, it doesn’t help that the key is totally unique.
Question: What is the standard called?
That looks to me like a Globally unique identifier, or GUID, and it is meant to be totally unique. They are sometimes used as database table primary keys when an auto-incrementing number is not appropriate. They are also used as identifiers in places like the Windows registry and as hardware device IDs.
