Using macOS Sierra: Disk Utility > File > New Image > Blank Image…, I created an encrypted .dmg file.
However when I open this .dmg (by entering password) and click "Info" in disk utility, it says:
Is encrypted: No
As I want to store some sensitive info (Credit Card info etc) in this disk and then upload it to cloud storage, I am worried if there is a bug in Sierra causing .dmg files to not be encrypted at all!
Is this normal? How can we verify if the disk is actually encrypted?
P.S. My filevault is On, and for my own Macintosh HD disk utility info says Is encrypted: Yes

The proper command to check if a dmg is encrypted or not is:
or more detailed with the encryption type:
Examples:
and/or
I can only guess why diskutil doesn't show that the image is encrypted. It's either a glitch or diskutil only rates FileVault as disk encryption.
