What does the -b switch for udisksctl do?

Question

I had to mount an encrypted external hdd using the command-line earlier this evening. Thanks to these instructions I was successful, but I'm left wondering what the-b switch for the udisksctl command does. I looked through the man page and there's no mention of it. Is it to signal that what's being decrypted is a block device?

The -b (--block-device) option is for choosing a block device like /dev/sdb1. You can find this out by typing udisksctl unlock --help for instance; replace unlock with mount, unmount and lock and you will see the -b option is used in the same way for all 4 cases.

The udisks command line tool udisksctl is a command-line program used to interact with the udisksd(8) daemon process.The -b option denotes a block-device like /dev/sdb1
