Why is MasterKey half Zero's after Assigning Password?

[aapollo]

Greetings,

I noticed half of the "Master Key" data returned by 'geli dump /dev/gptid/[disk-uuid]' changes to zero's (0's) after assigning a password to the volume in FreeNAS.

Does anyone know why?

Thanks.

Does geli dump -v do the same thing?

Hey, thanks for the reply. Yes, the same shortened key is displayed with the -v flag.

Might be worth asking on the FreeBSD forums. Leave a note here if you get an answer to your question.
