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.

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.

Blockchain tutorial 10: Diffie-Hellman key exchange
 
04:09
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.

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.

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 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?

The problem is inspired by the proliferation of large-scale distributed file systems supporting parallel access to multiple storage devices. Our work focuses on the current Internet standard for such file systems, i.e., parallel Network File System (pNFS), which makes use of Kerberos to establish parallel session keys between clients and storage devices. Our review of the existing Kerberos-based protocol shows that it has a number of limitations: (i) a metadata server facilitating key exchange between the clients and the storage devices has heavy workload that restricts the scalability of the protocol; (ii) the protocol does not provide forward secrecy; (iii) the metadata server generates itself all the session keys that are used between the clients and storage devices, and this inherently leads to key escrow. In this paper, we propose a variety of authenticated key exchange protocols that are designed to address the above issues. We show that our protocols are capable of reducing up to approximately 54% of the workload of the metadata server and concurrently supporting forward secrecy and escrow-freeness. All this requires only a small fraction of increased computation overhead at the client.

ID2S Password Authenticated Key Exchange Protocols

ID2S Password-Authenticated Key Exchange Protocols Abstract: In a two-server password-authenticated key exchange (PAKE) protocol, a client splits its password and stores two shares of its password in the two servers, respectively, and the two servers then cooperate to authenticate the client without knowing the password of the client. In case one server is compromised by an adversary, the password of the client is required to remain secure. In this paper, we present two compilers that transform any two-party PAKE protocol to a two-server PAKE protocol on the basis of the identity-based cryptography, called ID2S PAKE protocol. By the compilers, we can construct ID2S PAKE protocols which achieve implicit authentication. As long as the underlying two-party PAKE protocol and identity-based encryption or signature scheme have provable security without random oracles, the ID2S PAKE protocols constructed by the compilers can be proven to be secure without random oracles. Compared with the Katz et al.'s two-server PAKE protocol with provable security without random oracles, our ID2S PAKE protocol can save from 22 to 66 percent of computation in each server.

Transparent SSH Gateways
 
12:41
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.
