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.

While asymmetric (public-key) encryption does allow two parties to communicate security without exchanging keys, asymmetric encryption requires expensive computation for each message. Symmetric key algorithms are much more efficient. As a result, the two techniques are usually applied to establish and maintain a secure connection. Asymmetric encryption is used to protect the initial part of the connection where symmetric keys are exchanged. Once communicating parties agree on symmetric keys, symmetric encryption is used for the remainder of the communication.

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.

This is part 10 of the Blockchain tutorial explaining how the Diffie-Hellman key exchange works. In this video series different topics will be explained which will help you to understand blockchain. Bitcoin released as open source software in 2009 is a cryptocurrency invented by Satoshi Nakamoto (unidentified person or group of persons). After the introduction of Bitcoin many Bitcoin alternatives were created. These alternate cryptocurrencies are called Altcoins (Litecoin, Dodgecoin etc). Bitcoin's underlying technology is called Blockchain. The Blockchain is a distributed decentralized incorruptible database (ledger) that records blocks of digital information. Each block contains a timestamp and a link to a previous block. Soon people realises that there many other use cases where the Blockchain technology can be applied and not just as a cryptocurrency application. New Blockchain platforms were created based on the Blockchain technology, one of which is called Ethereum. Ethereum focuses on running programming code, called smart contracts, on any decentralized application. Using the new Blockchain platforms, Blockchain technology can be used in supply chain management, healthcare, real estate, identity management, voting, internet of things, etcetera, just to name a few. Today there is a growing interest in Blockchain not only in the financial sector but also in other sectors. Explaining how Blockchain works is not easy and for many the Blockchain technology remains an elusive concept. This video series tries to explain Blockchain to a large audience but from the bottom up. Keywords often used in Blockchain conversation will be explained. Each Blockchain video is short and to the point. It is recommended to watch each video sequentially as I may refer to certain Blockchain topics explained earlier.

What exactly is an API? Finally learn for yourself in this helpful video from MuleSoft, the API experts. https://www.mulesoft.com/platform/api The textbook definition goes something like this: “An application programming interface (API) is a set of routines, protocols, and tools for building software applications. An API expresses a software component in terms of its operations, inputs, outputs, and underlying types. An API defines functionalities that are independent of their respective implementations, which allows definitions and implementations to vary without compromising each other. A good API makes it easier to develop a program by providing all the building blocks. APIs often come in the form of a library that includes specifications for routines, data structures, object classes, and variables. In other cases, notably SOAP and REST services, an API is simply a specification of remote calls exposed to the API consumers. An API specification can take many forms, including an International Standard, such as POSIX, vendor documentation, such as the Microsoft Windows API, or the libraries of a programming language, e.g., the Standard Template Library in C++ or the Java APIs. An API differs from an application binary interface (ABI) in that an API is source code-based while an ABI is a binary interface. For instance POSIX is an API, while the Linux Standard Base provides an ABI”. To speak plainly, an API is the messenger that runs and delivers your request to the provider you’re requesting it from, and then delivers the response back to you. To give you a familiar example, think of an API as a waiter in a restaurant. Imagine you’re sitting at the table with a menu of choices to order from, and the kitchen is the provider who will fulfill your order. What’s missing is the critical link to communicate your order to the kitchen and deliver your food back to your table. That’s where the waiter (or API) comes in. ”AHEM” The waiter takes your order, delivers it to the kitchen, and then delivers the food (or response) back to you. (Hopefully without letting your order crash if designed correctly) Now that we’ve whetted your appetite, let’s apply this to a real API example. In keeping with our theme, let’s book a flight to a culinary capital – Paris. You’re probably familiar with the process of searching for airline flights online. Just like at a restaurant, you have a menu of options to choose from ( a dropdown menu in this case). You choose a departure city and date, a return city and date, cabin class, and other variables (like meal or seating, baggage or pet requests) In order to book your flight, you interact with the airline’s website to access the airline’s database to see if any seats are available on those dates, and what the cost might be based on certain variables. But, what if you are not using the airline’s website, which has direct access to the information? What if you are using online travel service that aggregates information from many different airlines? Just like a human interacts with the airline’s website to get that information, an application interacts with the airline’s API. The API is the interface that, like your helpful waiter, runs and and delivers the data from that online travel service to the airline’s systems over the Internet. It also then takes the airline’s response to your request and delivers right back to the online travel service . And through each step of the process it facilitates that interaction between the travel service and the airline’s systems - from seat selection to payment and booking. So now you can see that it’s APIs that make it possible for us all to use travel sites. They interface with with airlines’ APIs to gather information in order to present options back to us The same goes for all interactions between applications, data and devices - they all have API’s that allow computers to operate them, and that's what ultimately creates connectivity. API’s provide a standard way of accessing any application, data or device whether it is shopping from your phone, or accessing cloud applications at work. So, whenever you think of an API, just think of it as your waiter running back and forth between applications, databases and devices to deliver data and create the connectivity that puts the world at our fingertips. And whenever you think of creating an API, think MuleSoft.

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.

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?

This is a guide to using YubiKey as a SmartCard for storing GPG encryption, signing and authentication keys, which can also be used for SSH. Many of the principles in this document are applicable to other smart card devices. Keys stored on YubiKey are non-exportable (as opposed to file-based keys that are stored on disk) and are convenient for everyday use. Instead of having to remember and enter passphrases to unlock SSH/GPG keys, YubiKey needs only a physical touch after being unlocked with a PIN code. All signing and encryption operations happen on the card, rather than in OS memory. https://github.com/drduh/YubiKey-Guide I forgot to mention how to set up the touch feature of the yubikey, here are the commands: $ ykman openpgp touch aut on $ ykman openpgp touch sig on $ ykman openpgp touch enc on Get Tails: https://tails.boum.org/ Get a Chaos Key: https://altusmetrum.org/ChaosKey/ Get at least 1 Yubikey: https://www.yubico.com/store/ Get at least 3 USB sticks.

Dennis Felsch Ruhr-University Bochum Abstract: IPsec enables cryptographic protection of IP packets. It is commonly used to build VPNs (Virtual Private Networks). For key establishment, the IKE (Internet Key Exchange) protocol is used. IKE exists in two versions, each with different modes, different phases, several authentication methods, and configuration options. In this paper, we show that reusing a key pair across different versions and modes of IKE can lead to cross-protocol authentication bypasses, enabling the impersonation of a victim host or network by attackers. We exploit a Bleichenbacher oracle in an IKEv1 mode, where RSA encrypted nonces are used for authentication. Using this exploit, we break these RSA encryption based modes, and in addition break RSA signature based authentication in both IKEv1 and IKEv2. Additionally, we describe an offline dictionary attack against the PSK (Pre-Shared Key) based IKE modes, thus covering all available authentication mechanisms of IKE. We found Bleichenbacher oracles in the IKEv1 implementations of Cisco (CVE-2018-0131), Huawei (CVE-2017-17305), Clavister (CVE-2018-8753), and ZyXEL (CVE-2018-9129). All vendors published fixes or removed the particular authentication method from their devices’ firmwares in response to our reports.

In this tutorial we will cover how to set up a machine on SoftLayer so that you can SSH to the machine without entering a password. This utilises and RSA public/private key pair to make this happen. In addition we will 'security harden' the server by destroying the ability for any user to login over SSH using a password.
