cloud encryption: cryptomator

Here is a great solution for anyone who wants to encrypt their data before putting it onto the cloud.

https://cryptomator.org/

It's an open-source encryption software for PC, MAC, Linux, Android, and iOS. So every common plattform is supported.

How is it encrypted?

In short:
You get a realtime de-/encrypted container.

the password: scrypt
the files: AES-GCM (256 Bit)
(the filenames are also encrypted beforehand)

See the full documentation on that here: https://docs.cryptomator.org/en/latest/security/architecture/

pc windows example

Note

There are multiple files generated. good for cloud sync.
The structure looks for similar to the files and folders created with ENC DataVault by ENC Security
You get a "light" Version (which enables AES 256 bit) of that software with buying a Sandisk Cruzer USB Stick. I've bought the pro version allowing multiple, military-grade AES 512 and also AES 1024 bit containers.
=> cryptomator has a better usability

Use cases

In my case, I use it to safely share and access data between my windows pc, linux (ubuntu) and android smartphone.

On mobile, you get the option to sync your taken pictures encrypted into one container. for convenience, there is the option of entering your credentials to encrypted containers via fingerprint.

It would be possible to share cloud storage with other family members and keep private data protected.

You could also just encrypt your files locally on an external disk.

About the company: Skymatic GmbH

It's born as a german startup with the idea: there are a few cloud encryption tools available... but no one has made their code open source to be transparent and also more secure.

They also provide company licenses for implementing their technology into your own software or you can get an enterprise solution for encrypted file storing and sharing: cryptomator server https://server.cryptomator.org/

Introduction to IPv6 Course

What you actually learn:
How IPv6 works and whats different in v6 Protocols (instead of ARP, RIP, DHCP).
How many IP subnets to assign for different needs (sizes of houses, companies).
How to implement some security features, based on IPv6 Addresses.

1. From IPv4 to IPv6
Let's get started! From IPv4 exhaustion straight into IPv6. Let's see why it is a good idea to start working on your IPv6 network.

2. IPv6 Address Basics
Learn how to write IPv6 addresses correctly and calculate your first IPv6 subnets.

3. IPv6 Transition Mechanisms
What are the most used IPv6 Transition Mechanisms? Go through our list to learn the trends.

4. Deploying IPv6
SLAAC, ND, DHCPv6, DNS...don't let the acronyms fool you. Let's look at the best ways to take advantage of IPv6 characteristics.

5. Get and Register IPv6
Do you need to request your IPv6 allocation? Do you have an IPv6 allocation but you don't know how to register it? This section is made especially for you.

6. IPv6 Assignments and Addressing Plans
Learn IPv6 assignment best practices and get inspired for your addressing plan.

7. IPv6 and Security
Discover the different security aspects you need to consider when you deploy IPv6.

well.. who doesn't like badges 😉
