How to make Cipher Wheel
 
03:25
Check out the full article at http://www.stemlittleexplorers.com/en/how-to-make-cipher-wheel/ In this video, you will learn how to make Cipher Wheel or Cipher Disc which you can use to encrypt your messages that only people you choose can decipher. All you need is some Cardboard, Scissors, Ruler, Felt pen, Pen, Pin, Divider and Colored pencils. Also, great if you have a Protractor. Ciphering your message is simple: You rotate smaller disc for X places in Y direction. Then look at the letters from a bigger circle and write the letters from the smaller circle. Now you have coded message. A person who wants to decode the message needs to have the same Cipher wheel. You only need to tell him X places and Y direction and he can then align Cipher accordingly. Now that person reads letters from the smaller circle and writes the letters from the bigger circle. This is a great STEM Technology activity that Kids can use to learn coding and patterns. They will love it because the activity is mystical and secretive. Also, it's great for learning letters.

Creating a Keyfile in Debian 9.0 to lock an encrypted hard drive Part 5
 
10:14
This is Part five of a 5-part series which takes you through the complete installation process of the Debian Linux operating system with full-disk encryption. We also place the boot partition on an external USB flash drive. The focus will be on privacy and anonymity. Part 5 focuses on finishing up creating a key-file on an external USB flash drive that will be used to unlock the encrypted internal Solid State Drive in our Debian system. This key drive can be hidden or carried with you to prevent anyone from accessing your computer when you are away. This configuration is designed to give us a secure and private operating system. From here we can add and configure additional privacy and anonymity tools such as Tor, Whonix and VPNs. What you will need: 1. Computer (Laptop or desktop) 2. Internet connection (wired preferred) 3. Installer Media (CD-ROM or Flash Drive) 4. SSD Hard Drive 5. USB Flash Drive (small profile) 6. Time and Patience You can find the other parts of this tutorial here: Intro: (overview and gathering materials) https://www.youtube.com/watch?v=h_-19EyKdLs&t=180s Part 1: (Initial set-up and format encrypted drive) here https://www.youtube.com/watch?v=etzJAG_H5F8 Part 2: (partition encrypted drive and download software form mirrors) https://www.youtube.com/watch?v=yJdBIigQcVw Part 3: (install Grub boot-loader and finish installation) https://www.youtube.com/watch?v=JyA4owRVUls Part 4: (Creating key file and moving it to boot drive) https://www.youtube.com/watch?v=upOqR4HPi60 Part 5: (removing pass-phrase key and shredding copy of key-file on the hard drive) https://www.youtube.com/watch?v=APjHjCUtRT0 Here is the website where you can download the latest version of Debian Linux https://www.debian.org/ Check out my video on installing and verifying Debian: https://www.youtube.com/watch?v=N7oE0QaK540 The software for writing the installer to a boot-able flash drive and can be found here: Win32 Disk Imager https://sourceforge.net/projects/win32diskimager/ If you prefer to write your installer image to a CD-ROM, I would highly recommend Power ISO https://www.poweriso.com/ The Anonymous Guide can be found here: https://anonguide.cyberguerrilla.org Donate Bitcoin: 1Pf7Uwc2XyrMhjaKxzqszJsvWAdCPhdFR2

DEF CON 24 - Jmaxxz - Backdooring the Frontdoor
 
38:38
As our homes become smarter and more connected we come up with new ways of reasoning about our privacy and security. Vendors promise security, but provide little technical information to back up their claims. Further complicating the matter, many of these devices are closed systems which can be difficult to assess. This talk will explore the validity of claims made by one smart lock manufacturer about the security of their product. The entire solution will be deconstructed and examined all the way from web services to the lock itself. By exploiting multiple vulnerabilities Jmaxxz will demonstrate not only how to backdoor a front door, but also how to utilize these same techniques to protect your privacy. Bio: Jmaxxz works as a software engineer for a Fortune 100 company, and is a security researcher for pleasure. His FlashHacker program was featured in Lifehacker’s most popular free downloads of 2010. More recently he has contributed to the node_pcap project which allows interfacing with libpcap from node. His other interests include lock picking and taking things apart.

What Is Bitcoin?
 
01:29
"... Bitcoin is better than currency ..." says Mr. Bill Gates!! What is bitcoin? Bitcoin is an experimental system of transfer and ownership verification based on a peer-to-peer network with no central authority. The initial application and the main innovation of the network Bitcoin is a decentralized electronic cash system that bitcoin is the unit of account. Buy bitcoins from this link: https://goo.gl/CdCc87 and receive $10 bitcoins as a bonus!! Bitcoin works with software and a protocol that allows users to issue and manage bitcoins collective and automatic transactions. As a free protocol (open source), it also allows inter-operability of software and services that use it. As the bitcoin currency is both a means of payment and a store of value. Bitcoin is designed to regulate itself. The limited inflation Bitcoin system is distributed homogeneously by computing power through the network, and is limited to 21 million units divisible to the eighth decimal. The smooth functioning of trade is secured by a general organization that everyone can examine, because everything is public: the basic protocols, cryptographic algorithms used, the operational visiting programs, account data and discussions of developers. Possession of bitcoins is marked by a series of numbers and letters that make up a virtual key to the expenditure of bitcoins associated with it in the register. A person may hold several keys together in a "Bitcoin Wallet", a "key ring" web, software or hardware that provides access to the network to perform transactions. The key fob can view the balance in bitcoins and public keys for receiving payments. It also contains (often in encrypted form) the private keys associated with these public keys. These private keys must remain secret because their owner can spend bitcoins associated with them on the register. Any medium (key) agrees to keep following symbols constituting your keyring: paper, USB key, memory, etc. With the right software, you can manage your assets on your computer or your phone. To have bitcoins to an account, you must be a holder of bitcoins you gave, for example in exchange for a good or go through an exchange platform that converts conventional currency bitcoins or having earned participating in collective control operations of currency.

How Do I Tails?: A Beginner's Guide to Anonymous Computing
 
01:16:30
This talk serves as an introduction to The Amnesic Incognito Live System and anonymous computing. It covers why privacy is important, the various features of the operating system, and also touches on some basics of threat modeling and operational security. This talk was given at DEF CON 23 in the EFF's Crypto & Privacy Village. Due to limited village space, there were actually two presentations operating at the same time, hence the background noise. The microphone that I was using was pretty poor quality, and as such the audio isn't the best. I have taken the time to transcribe the audio to try and compensate for these problems, so try giving the captions a run. When the audio cuts out, it is due to someone speaking off screen and I removed the audio to protect their privacy. Since this presentation was given in August of 2015, there are portions that are now out of date or irrelevant. I will attempt to provide corrections and updates either in the description or annotations on the video itself. If you notice something that needs correction, send me a message and I'd be happy to tweak it. Big thanks to my buddy Kyle Hinckley, a.k.a. The Weirdist for his help in getting this project edited and rendered.

Web of trust
 
10:27
In cryptography, a web of trust is a concept used in PGP, GnuPG, and other OpenPGP-compatible systems to establish the authenticity of the binding between a public key and its owner. Its decentralized trust model is an alternative to the centralized trust model of a public key infrastructure, which relies exclusively on a certificate authority. As with computer networks, there are many independent webs of trust, and any user can be a part of, and a link between, multiple webs. The web of trust concept was first put forth by PGP creator Phil Zimmermann in 1992 in the manual for PGP version 2.0: This video is targeted to blind users.

Let’s dive right in with a demo. Sooooo, Let’s Get Started. The first thing you’ll need to do is to make a backup of your USB drive, as all data will be erased when creating an Encrypted USB drive. So, once that’s done, launch Disk Utility and then insert your USB drive in an available USB socket, this is basically known as Mounting the drive. On the sidebar of the Disk Utility Window, click on the USB drive just mounted, in my case, it’s an 8 GB USB shown here. Now, click the Erase tab here and then from the drop down list shown here, select either, Mac OS Extended (Journaled, Encrypted) or Mac OS Extended (Case-sensitive, Journaled, Encrypted). Basically, Case-sensitive option allows you to have files and folders with the same name using different case, for example, a folder named music, all small caps, is different from one named Music with a capital M. In our case, I’ll be using, Journaled, Encrypted without Case-sensitive option. It should be mentioned, an Encrypted USB drive can only be accessed on Mac systems. Therefore; continuing on, after selecting the encryption format, enter a name if you wish for the USB drive and then click the Erase button. You are now presented to enter and verify a chosen password and a hint if you wish, then click on the Erase button to begin the encryption process. I’ll just time-lapse the encryption process at this point. Incidentally, the process for me took about a minute and a half to complete. Once completed, simply close the Disk Utility Window and eject the USB drive by dragging it to the Trash as shown and remove the USB drive. Now; whenever you insert the USB drive, you will be presented with the following window, asking to enter a password to Unlock the USB drive, do so and click the Unlock button to Mount the USB drive. And that’s all there is to it, encrypting a USB drive could not be more simple. Thanks for watching and thumbs-up if you liked this video, and please, don't forget to subscribe to be notified of the next Episode. Thanks and Peace.

Ethereum-109 MyEtherWallet signed message, signature
 
09:53
Ethereum-109 MyEtherWallet signed message, signature With MyEtherWallet, you can send a message (with your signature on it) to your friend, and your friend can be sure that the message was sent by you (by verifying the signature). Step 1: Create your own wallet using MyEtherWallet and keep both keys. I use the following for demonstration: Private key (PrK) 05f7b61d8ebb7111be30c28c105b17c1a19e20a9a189d9a05f452f1fdf4e56c4 Address (Adr) 0x9687A96cd4699D3B181d592c15BE8D842891DB56 Let's say A will send a signed message to B Then A keeps PrK and B keeps Adr (B will know "0x9687A96cd4699D3B181d592c15BE8D842891DB56" is A's address) Step 2: Create a signed message Open webpage https://www.myetherwallet.com/signmsg.html Access your wallet using the above Prk Type the message: It's urgent, please deposit HK$50,000 in my account XXX-XXX-XXX Press "Sign Message",you will get the following { "address": "0x9687a96cd4699d3b181d592c15be8d842891db56", "msg": "It's urgent, please deposit HK$50,000 in my account XXX-XXX-XXX", "sig": "0xb4989cb90b433fc05b96ce54a6b7317244b1f9c4f6bea5c5efbadff3025ed5613181e02ca9dff97c7680c603bb63790869ceabca42569f29a646a0fef24820131b", "version": "2" } Step 3: Send out the following by E-mail, Whatsapp or .... It's urgent, please deposit HK$50,000 in my account XXX-XXX-XXX 0xb4989cb90b433fc05b96ce54a6b7317244b1f9c4f6bea5c5efbadff3025ed5613181e02ca9dff97c7680c603bb63790869ceabca42569f29a646a0fef24820131b Step 4: B Verify the signature Open webpage https://etherscan.io/verifySig Fill in as shown in the video Press verify, that's it. The message is 100% from A (or anyone holding the Private Key) If someone sends the message without the correct signature, B cannot verify it. Step 2a: Sign message using an offline mobile Bookmark this "file:///storage/emulated/0/MEW/signmsg.html" in mobile Open the above webpage (you should have a copy of the MyEtherWallet web-site as shown in 107) If you have a QR-code of the private key in the mobile, use QR-Droid to get it. Access your wallet using the private key Type in the message Press "Sign Message", Signature appears To move the above signature to online device, here's the trick 1. copy the signature 2. open "file:///storage/emulated/0/MEW/index.html#offline-transaction" 3. paste the signature in "Signed Transaction", you will have a QR-code (MyEtherWallet can generate the QR-code for any text in the box) 4. scan the QR-code using online mobile or computer, you then have the signature

DEF CON 24 - Jmaxxz - Backdooring the Frontdoor
 
38:38
As our homes become smarter and more connected we come up with new ways of reasoning about our privacy and security. Vendors promise security, but provide little technical information to back up their claims. Further complicating the matter, many of these devices are closed systems which can be difficult to assess. This talk will explore the validity of claims made by one smart lock manufacturer about the security of their product. The entire solution will be deconstructed and examined all the way from web services to the lock itself.
