Does TRIM work with encrypted Ubuntu?

Question

ubuntu

Does TRIM work with encrypted Ubuntu system tools? And doesn't that affect security?
I remember Truecrypt doesn't like TRIM, but here I don't know..

Answer 1

trim is a command that signals to the ssd controller that the block can be freed. Encryption here kagbe is completely out of work.
There are several points that theoretically can make it easier for an attacker to break in, but they do not lie in a practical plane.
you can read askubuntu.com/questions/399211/is-enabling-trim-on... for enlightenment.
