How is the USB stick formatted? Some formats (especially those on a USB stick) do not have permissions or any access control.
What is stored on the USB stick? An OS or Time Machine backup? Those cannot be modified.
> is it possible to open the encrypted file with windows afterwards?
I guess not. But I have sometimes made an encrypted .zip file although the standard zip encryption is very weak and is easily cracked.
zip -re output.zip input_file.txt input_folder
zip -h show help
-r recurse into directories
-e encrypt

Veracrypt is a multi-platform drive encryption option (it was forked from the original True-Crypt project when the original developers abandoned the project):

ExFAT has no permission capability. There is no way to restrict access.
Thanks for your reply Barney
i will check this evening but I believe I formatted in exfat to keep windows compatibility…
not a TM backup support, just some folders and kids pictures
Make an encrypted disk image on the SD card.
Thank you Guys for your feedback
the encryption is a good idea. I discovered how to do it with Disk utility app, but is it possible to open the encrypted file with windows afterwards?
I finally format the stick in APFS and adjust access permission
Thx for your help
