How to disable cryptswap?

Question

How can I disable cryptswap? I would like an unencrypted swap like before.

This is on an ubuntu 9.10 system.

I followed this explanation (currently down, see its google cache), and it worked without any problems.

To remove crypt mapping use something like this:

cryptsetup remove cryptswap1

Or just reboot the computer. If you remove/comment lines from /etc/crypttab and /etc/fstab, encrypted swap will not created on the next boot.

If you used cryptsetup to create your encrypted swap, you can easily reverse the process:

Currently your /dev/hda? will be mapped to cryptswap (something like cryptsetup luksOpen /dev/hda4 cryptswap)

so first disable the line in /etc/crypttab that mentions cryptswap and remove the cryptswap line from /etc/fstab

Then use cryptsetup to remove the crypt mapping.

At this point you can remove the swap partition and recreate it as an ordinary partition
