1. Execute below provided commands to encrypt an RBD image.
2. Use the rbd info command to inspect the properties of the encrypted RBD image.
3. Observe that there is no explicit indication of whether the image is encrypted or not.

rbd create --size 1G devpool/test-img
rbd encryption format --cipher-alg aes-256 devpool/test-img luks2 /home/user/passphrase.bin
rbd info devpool/test-img
rbd image 'test-img':
size 1 GiB in 256 objects
order 22 (4 MiB objects)

I expected the output of the rbd info command to include a clear indication or flag confirming that the RBD image 'test-img' had been successfully encrypted using the AES-256 cipher algorithm. This indication would allow me to verify that the encryption process was completed as intended.
