Daten Verschlüsseln Einfach Erklärt - 4/5

How to encrypt you data - easily explained

In recent years the capacity of our harddisks,

USB drives and sd-cards has increased rapidly.

Which means we carry more data around with us.

Which is handy.

But leads to two big problems if we lose a USB-Stick or a laptop.

Of course replacing a device can be quite expensive.

But atleast a it is possible.

Even worse is the uncertainty of what could happen to your lost data.

Especially if you lost important files.

Or personal files that belong to you or someone else.

But even for very big harddrives,

USB-Sticks and external harddrives

you can solve both problems with one solution:

With encryption.

With a program like "Truecrypt" you can

either encrypt the full storage medium

or simply create so called

"encrypted file containers".

An encrypted harddisk or such a "file container"

can be compared to a "digital" safe.

Which you can only open with the right combination.

So how does this solve both issues?

Once you have saved your data in an encrypted file container

you can create as many copies as you like.

Which makes it much easier

to spread those containers on different devices.

You can save them at home,

give them to your friends,

or if absolutely neccessary in the "cloud".

Just like most IT-experts say:

Data only exists

if it's saved in atleast 3 different locations.

So even if you lose a drive

because your laptop gets stolen

or your house burns down

or a magpie is stealing your brand new USB-Stick

You'll still sleep save and sound

because you are the only person

that knows the passwort

and can read your data.

So here's a short explanation

how to create such a container

so you can sleep well.

First you have to download "Truecrypt"

from a site that you trust.

You can find some links in the video description.

Once you have it installed and started

you can click on "create volume" which

opens a simple "wizard"

This will guide you through the process step by step.

Most of the options are self explaining.

Some are explained by the program.

Once you have everything set up

"Truecrypt" asks you

to randomly move your mouse.

It will use your movements to

generate random numbers

which it needs for secure encryption.

Ok... that should be enough...

Really... even longer?

Ok...

Finally you are a proud owner

of a brand new encrypted file container.

The development of truecrypt has been

discontinued in 2014. But version

7.1a is still a good choice.

Because experts have read and checked

the whole sourcecode of this version

for back-doors and bugs.

And haven't found anything.

Alternatives to "Truecrypt" are

"Ciphershed" and "Veracrypt"

which are based on Truecrypt.

But these programs have not been

audited as well as truecrypt.

Check the video description for

a link to truecrypt and to a comparison

of different file encryption software.

But remember, encryption is only

as strong as your password.

So we recommend our very first film

which explains how

to come up with a good and easy password.

Alright

have some fun with encryption

and don't forget to make backups!

Thank you for watching.
