# DESCRIPTION:
# 'zfs change-key -o' should change the key format.
#
# STRATEGY:
# 1. Create an encryption dataset with a passphrase key format
# 2. Unmount the dataset
# 3. Verify the key format is passphrase
# 4. Change the key format to hex
# 5. Verify the key format is hex
# 6. Attempt to reload the dataset's key
# 7. Change the key format to raw
# 8. Verify the key format is raw
# 9. Attempt to reload the dataset's key
#
