Full disk encryption after installing Kali Linux

I've installed Kali Linux as the only OS(which it will remain) on a 100GB partition on the hard drive in my laptop. I didn't set up the encryption while installing it and I would now like for it to be fully encrypted. I was able to encrypt a previous hard drive that had Windows 7 on it, very easily, but it appears as if I no longer have the same options within Kali Linux.

Is it possible to encrypt my hard drive at this point, or will I have to reinstall Kali Linux, and if it is possible, can you explain how to?

True crypt supports full disk encryption, however they have shutdown the project and said publicly not to use the product

Some people think it was a warrant canary (the shutdown) and so far the truecrypt audit is coming up clean.


Google truecrypt full disk encryption in ubuntu

this should set you in the right direction

Thank you for answering.

I actually did a re-install and found out that Kali Linux has it's own encryption. I would assume that it contains a backdoor, so I'll be re-installing again...
