dislocker-metadata returns multiple Recovery Key GUIDs

[linuxgnuru]

NOTE: I have not tested to see if this is unique to MacOS or if this is also in Linux

We use a server to retrieve passcodes using recovery keys and when using:

sudo dislocker-metadata -V /dev/disk4s4 | grep Recovery

it returns 2 different keys with the same time stamp (i changed the last digits for security but every character in the key is different):

Tue Jan 23 14:23:59 2024 [INFO] Recovery Key GUID: '4C672E5A-D0DB-4749-BD11-123456789012'
Tue Jan 23 14:23:59 2024 [INFO] Recovery Key GUID: '42FC9468-612A-4348-BF31-123456789012'

I was wondering is this a bug? Which key is valid for me to enter into our server to get the decrypt password?

Although multiple "Recovery Key GUIDs" were returned, is there any pattern? Is the last Recovery Key GUID always the correct one?

Do you know how to generate multiple 'Recovery Key GUIDs'?
