Problem with encryption
If the Encrypt contents to secure data option is unavailable (grayed out and you can't select the box), encryption may not be enabled or available on your device.
However, it is also important to note that while encryption adds an extra layer of security, it is not foolproof. It is essential to regularly update your passwords and encryption keys and use strong, unique combinations for each file. Additionally, always be cautious about sharing decryption keys and only use trusted software encryption.
