Required to fetch few details on FileVault I require to fetch below few details on FileVault enabled users.
1)Private recovery key set or not
2)Institutional recovery key set or not
3)Authorized on every logon - supported or not.
Which commands will help us to fetch these details for File-Vault enabled users.
I want to get these details as a part data collection.
From man fdesetup :

haspersonalrecoverykey [-device] [-verbose]
    Returns the string "true" if FileVault contains a personal recovery key.

hasinstitutionalrecoverykey [-device] [-verbose]
    By default, this will return the string "true" if FileVault contains an
    institutional recovery key. On CoreStorage volumes specified using the
    --device option, this will return the hex representation of the public key
    hash instead of "true". The hash option is not supported for APFS volumes.
    This will return "false" if there is no institutional recovery key installed.

usingrecoverykey [-verbose]
    Returns the string "true" if FileVault is currently unlocked using the
    personal recovery key.

supportsauthrestart
    Returns the string "true" if the system supports the authenticated restart
    option. Note that even if true is returned, this does not necessarily 
    mean that authrestart will work since it requires that FileVault be enabled.
