Extend encrypted primary partition to fill free space without decrypting?

I'm finding a lot of advice online explaining how to enlarge an unencrypted file system partition but very few helpful ones for my situation explaining how to do so with an encrypted partition without having to decrypt. I recently created a disk image from my previous 128GB drive and restored it on a larger 500GB drive and I'd like to expand to use all the remaining unallocated free space. I already used the default Disks app to resize /dev/sda2 to use the full 500GB but I'm unsure what to do next. Here's some info on my current disk/partition situation:

Also, I'd like to increase the swap space to 2GB but I'm not sure how to do that either!

Any help would be greatly appreciated :slight_smile: :slight_smile:
