Encrypt stuff guide

This thread will be a collection of resources on how to use encryption, tool use suggestions and where possible, usage explanations.

I’m fine with reading technical documents, however I also value time and the ability to convey a point, without a huge time investment. The easier and more clearly encryption can be used, the better everyone will be.
Be it an individual or some sort of state agency / boogeyperson, more layers and protections are a good thing. Having protections does not make one a criminal, either.

CryptSetup LUKS guide. There are command syntax examples and console response dialogs.

Cryptsetup is nice, as it also handles mounting of drives and partitions. If you are unable to mount a drive, you will likely need to install cryptsetup. This should also work to mount any TAILS persistent volumes you have setup.
For more info on DM-Crypt (cryptsetup), the Arch wiki is a great resource.

Samples of flow (1st link)
01 step: install cryptsetup (dm-crypt)
02 step: confirm your drive target and valid partition (gparted or parted to get your /dev/(drive))
03 step: initialize your drive

# cryptsetup -y -v luksFormat /dev/xvdc

(This is setting up your passcode to access drive)
04 step:

# cryptsetup luksOpen /dev/xvdc backup2

(Mounts newly configured drive)
05 step: format the LUKS partiton (needless to say, you really want to have the correct drive or you have lost data on the drive you are using)

# dd if=/dev/zero of=/dev/mapper/backup2

(This will take quite some time. Let the cursor do it’s work, check your hdd led to confirm activity)

Google Data Mining

I wanted to share the details listed in Google services with your history. will let you check through search history, advertising settings and so on.

To clear them, you want to click the vertical … bar and select Delete options. Pick advanced and All Time.
You will need to do this for each record set / option of google services. If you use chrome and log in, you will surely see some data there. Personally, I think Google is playing a little Cover-Your-Ass by disclosing these tools to general users. Along those lines, I find it hard to pretend other major data players, do not do the same thing with user data.

Here is a guide on the privacy settings. Remember your GPS history is there and that some content will persist, even after a clear all history. You ‘Pause’ the tracking services. Interesting wording there.
