Not sure is this is the best place to post this question, but wondering what is the best way to encrypt a usb drive?

Want to be able to carry an encrypted flash drive with me but also be able to unlock it, if possible, on various OSes. Preferably with some kind of portable software. Something similar to the method that comes with the Kingston Data Traveler USB drives.

Edit: Seems like Veracrypt and Cryptomator are the best options to check out. Thank everyone!
