How to generate an EOS key pair safely OFFLINE. (make a new private key and public address)
 
11:57
STEPS TO GENERATING AN EOS KEY PAIR OFFLINE • 1. Download key generator page to your computer or a flash drive: https://nadejde.github.io/eos-token-sale/ (Use at your own risk and discretion) Put it somewhere easily accessible when you boot into Linux, such as C:\eos-key\ or on a separate flash drive. I recommend not putting it on your desktop, nor in your "Documents folder", nor in a deeply nested folder. • 2. Download Ubuntu operating system (to be installed on a flash drive): https://www.ubuntu.com/download/desktop • 3. Follow the instructions for your operating system: https://tutorials.ubuntu.com/tutorial/tutorial-create-a-usb-stick-on-ubuntu#0 A. (Windows users) If you are using Windows, follow these instructions: https://tutorials.ubuntu.com/tutorial/tutorial-create-a-usb-stick-on-windows B. (Mac users) If you are using Mac, follow these instructions: https://tutorials.ubuntu.com/tutorial/tutorial-create-a-usb-stick-on-macos C. (Ubuntu users) If you are already using Ubuntu, follow these instructions: https://tutorials.ubuntu.com/tutorial/tutorial-create-a-usb-stick-on-ubuntu • 4. Disconnect your Internet cable • 5. Reboot your machine. Boot straight into Ubuntu using your flash drive (if it doesn't automatically boot using your flash drive, you may have to configure your boot drive options in BIOS by pressing "DEL" at startup screen when you first turn on your computer) • 6. When the Ubuntu operating system has finished booting, load the saved webpage for generating your keypair (Where you saved it in Step 1 above). Click "Generate EOS key". • 7. Print or write down your new key pair (EOS public address and private keys) Important Note: If you write it by hand, write the private key multiple times and triple check it. You can always derive the public address from the private key later if you need to. You cannot derive the private key. If that is lost, you will have lost your entire account and all associated funds. Note: To print from Ubuntu, you may need to have the drivers for your printer if Ubuntu does not recognize your printer model. • 8. (Optional step) See my other video on how to use the Greymass wallet to use your newly generated keypair for your "owner" or "active" permission levels: https://youtu.be/K3YyzRrPcO8 - - - - - - - - - - - - - - - - - - - - - - - - Disclaimer: The views expressed in this video are strictly my own and are not to be construed as trading advice.

How to Use Putty with SSH Keys on Windows
 
01:40
In this tutorial, we will demonstrate how to use PuTTY with SSH keys in windows. Don't forget to check out our site http://howtech.tv/ for more free how-to videos! http://youtube.com/ithowtovids - our feed http://www.facebook.com/howtechtv - join us on facebook https://plus.google.com/103440382717658277879 - our group in Google+ In this easy step by step tutorial, you will learn how to use PuTTY as an SSH client in Windows. PuTTY is communication software available freely over the internet, which uses several network protocols including SSH. Logging in using PuTTY SSH keys allows the only those people who have a valid key pair, which further prevents any threat of unwanted hacking of data. Step#1: Configuring PuTTY terminal First of all, open up the PuTTY terminal. Over here, enter the host for the server which you want to connect to. Let's enter an IP address of one of the host here and leave the port to default. Step#2: Authorization With that done, let's move to the SSH option in the category portion, expand it and then click on the "Authorization" option. Here, browse for the Key File which will be automatically made when configuring this connection. Locate the file and then click on the OK button. Step#3: Connecting to SSH Server Once you are done with that, a terminal will open up and will prompt you for the username. Specify the username and hit enter. After that, the connection would be established completely, enabling you to perform any tasks depending upon the permissions set by the administrator. Step#4: Generate SSH Key Now let's see how we can generate the SSH keys. For that, open up the Putty key generator. Over here, click on the Generate button next to the "Generate a public/private Key pair" option, in the Actions section. Step#5: Encrypting and saving SSH Key You can also change the type of parameters according to your requirements, and even change the bits over here. When prompted to generate some randomness, keep moving the cursor over the blank screen over here. This step is basically used by the application for securing the encryption. Random movements can be hard to re-generate and the sequence produced by your movements is calculated by the application. Once the process completes, it will show you the encryption key in the preview area. To save this key, click on the Save Private Key button and it will prompt you with a notification asking you whether you want to create a key without a passphrase. Hit yes to ignore it for now and then specify the location for the file. Your PuTTY SSH key file would be saved with the ".ppk" extension. And that pretty much covers the basics of using PuTTY with SSH keys in windows.

How to Setup a User with Public-Key-Only Authentication with SSH Key Pair
 
05:43
In this video, you will learn how to setup a user with Public-Key-Only Authentication using an SSH Key pair. This includes creation of a test account and verification of connection to EFT using CuteFTP as a client. We will also create an SSH key pair (public/private) with the use of the client; your user's ability to do so with their client will vary depending on the client used. Afterwards we will review how to import the needed public key in EFT and how to assign it to the user in question. Finally, we will use a method for confirming the connection is occurring via the SSH Public Key as expected. Still have questions?

HakTip - Linux Terminal 101: Typing Less with Keyboard Shortcuts
 
04:54
Today we're typing less with keyboard shortcuts! Once you think you've learned the easiest way to input a command or control, there seems to always be a new way! My goal is to never need to use my mouse... but that may take some time. Here's a few tips that can help! Moving your cursor around: Use CTRL-A, E, F, B to move the cursor to the beginning, end, forward one character, or backwards. Typing clear will clear out your terminal. Edit the text in your command: Use CTRL-D, T to delete or exchange the character at your cursor's location. Use ALT-L, U to convert characters to lowercase, or convert characters to uppercase. Cutting and pasting: This is also called 'killing and yanking'. Use CTRL-K, U to kill text from the cursor to the end of the line or from the beginning to the cursor. Use ALT-D, and backspace to Kill text from the cursor the the end of the word or from the cursor to the beginning of the word. Use CTRL-Y to take text that has been cut and insert it at the cursor location. We're back with keyboard shortcuts! We've already gone over the tab completion in a previous HakTip, so we'll now check out some other commands. Instead of tab, you can also use ALT-? to show a list of completions you can use, and ALT-* to insert all of those possibilities. Check out the bash man page under Readline to see more completion commands. What are your favorite shortcuts for text completion? Make sure to email me [email protected] with your thoughts. And be sure to check out our sister show, www.hak5.org for more great stuff just like this. Dont forget to check out our new show Threat Wire, for internet privacy and security news at youtube.com/techfeed. I'll be there, reminding you to trust your technolust.

swap keys around using a GUI (Graphical User Interface) called xkeycaps, which you can download from the Ubuntu Software Center. This program (though a GUI) is normally run by typing "xkeycaps" in a terminal. You can, however, add the program to Applications/Accessories by means of adding it to Systems/Preferences/Main Menu. It is easy to swap around any keys by (1) moving the cursor to the first key (2) right clicking the key (3) select "swap" (4) move to the other key you want to swap, (5) click. You're done. This is a temporary method, but you can make any of these changes stay put after rebooting. There is a nomenclature error in the video: "Grave", not "Acute". There are 5 videos: SWAP KEYS 1 through 5

Kerberos - authentication protocol

At 4:30: A mistake: step 3: When the file server gets the token, it "decrypts" (not "encrypts") the token with the secret key shared with TGS. In Greek mythology, Kerberos is a dog with three heads. But today I will not talk about the dog. Kerberos is an authentication protocol for client/server applications. I will demonstrate with an example how Kerberos works.

How To | Configure Root SSH on Kali Linux
 
06:00
Hello Everyone, Today we will show you, how to configure root SSH on Kali Linux . The SSH protocol (also referred to as Secure Shell) is a method for secure remote login from one computer to another. It provides several alternative options for strong authentication, and it protects the communications security and integrity with strong encryption. Using Linux with different mind set is what sets the difference from a Black Hat, and a traditional Linux user. Let's see how secure shell works , secure shell is a network protocol for securing data that flows between a client and a server over a public network such as the internet when a client connects to a server it needs to be verified so the transaction can be considered secure one of the methods to authenticate the client is an exchange of cryptographic keys after the server successfully authenticate the client a tunnelled connection is established them secure shell provide encrypted file transfer between the client and the server . Also provide participants with the opportunity to have a Hands-On Experience in using effective Identity Security Solutions to deter malicious activities. If it isnt usable, nobody uses it. Lets see what parameters we have to used , and what we can do and why . - MaxAuthTries Specifies the maximum number of authentication attempts permitted per connection. Once the number of failures reaches half this value, additional failures are logged. The default is 6. Setting the value to 3 will mean that your server will only allow 3 login attempts before locking you out. But black hats they can do more ,security is a myth the term is not enough you can bypass the MaxAuthTries Security is mostly a superstition. It doesn't exist in NATURE (Black hat mind set) . - MaxSession Specifies the maximum number of open sessions permitted per network connection. The default is 10. To allow control of the number of multiplexed sessions supported over a single TCP connection. This allows increasing the number of allowed sessions above the previous default of 10, disabling connection multiplexing (MaxSessions=3) Disclaimer : This Video is for Educational Purpose Only, what you do is your responsibility and Black Hat Ethical Hacking or anyone involved, is not held accounted for if any damage for any reason occurs .

Multi-factor Authentication Using Keys
 
13:10
This webinar will be a hands-on learning session, which will demonstrate the hidden features of Secure Shell (SSH) protocol live. Key learning areas of the session are: Multi-factor authentication using keys Inline command execution Automatic command execution Transparent SSH gateways Secure tunnel creation SSH connection multiplexing Traditionally *NIX servers were remotely accessed using Telnet, but since the advent of SSH, Telnet has been phased out. Today, all the UNIX and Linux operating systems support SSH. Unlike traditional Telnet, SSH is a far more advanced protocol and muti-purpose protocol. Besides giving encrypted remote shell access, it also provides features like secure file copy (both pull and push methods), secure X11 forwarding encryption services for other clear text traffic, and SSH connection multiplexing to reduce resource usage. It provides secure services like confidentiality using encryption, secure key exchange by using Diffie-Hellman and RSA based key exchange, and provides data compression. Since SSH has replaced Telnet, administrators too have started using it in the same way as Telnet, which is just for remote shell access. While SSH can be used in many ways and, if used correctly in right situation, can save a lot of work and time for administrators. This presentation will disclose some of the hidden features of the SSH protocol, which may not be used generally but can be quite handy in odd situations.

Provo Linux User Group - 8/17/2015 - Aaron Toponce - "Crypto Algorithms"
 
01:26:43
Aaron Toponce will talk about symmetric and asymmetric cryptography, and the current cipher algorithms covering them, such as RSA, AES, and ECC. He'll talk about how encryption and decryption work, as well as digital signatures and verification. He'll include the Diffie-Hellman key exchange, and the SSL/TLS handshake. Further, given the disaster on OpenSSL during the year of 2014, he'll talk about the major threats that compromised online security with SSL and TLS. He'll explain the differences between: * SSL 2.0* SSL 3.0* TLS 1.0* TLS 1.1* TLS 1.2* TLS 1.3 (draft status) He'll talk about the implemented ciphers and hashes, including their advantages and shortcomings. He'll discuss the attacks that took advantage of these shortcomings, such as Heartbleed and POODLE. He'll show how system administrators how to properly secure their web, mail, and other servers that require SSL/TLS. Finally, he'll discuss OpenPGP and OpenSSH concepts. By the end of this talk, the basic mysticism that is crypto should be all cleared up.
