Installing Third-Party Modules on Python In the Python folder, in scripts, there is a pip application. The pip tool is meant to be run from the command line. Through this tool on Windows, you can install modules for Python. Guide: Type %localAppdata% on start or Run, go to Programs, Python, Scripts and add pip to this path or use this path: "C:\Users\youruser\AppData\Local\Programs\Python\Python36-32\Scripts\pip " The path depends on the Windows username and Python version. 1. Open CMD or Command Prompt. 2. Paste the path C:\Users\youruser\AppData\Local\Programs\Python\Python36-32\Scripts\pip 3. Add install nameofthe module example C:\Users\youruser\AppData\Local\Programs\Python\Python36-32\Scripts\pip install pyperclip 4. Press Enter To uninstall it just change install to uninstall and confirm. Thank you for watching! by EasyComputerUse

GNS3 Talks: Python for Network Engineers with GNS3 (Part 11) - Paramiko, SSH, Python and Cisco
 
14:13
Learn Python programming with GNS3. In this series of videos I will show you how you can quickly and easily program Cisco networks using Python. ================================ Script on GitHub: ================================ https://github.com/davidbombal/python... ================================ Install Paramiko: ================================ apt-get update apt-get install python -y apt-get install build-essential libssl-dev libffi-dev -y apt-get install python-pip -y apt-get installpython-dev # You may need to install this as well pip install cryptography pip install paramiko ================================ Al's GNS3 community entry: ================================ https://gns3.com/discussions/docker-u... Transcription: Since I started recording the Python for Network Engineers videos, the number one request has been to demonstrate the use of SSH with Python and Cisco devices. So as we can see here, there are a number of requests for SSH and Paramiko. This is one of multiple videos teaching you network programmability using Python and GNS3. Al, as an example has even gone further and created an entry on the GNS3 community showing you how to install Paramiko and Netmiko on the Ubuntu client that I've been demonstrating in these videos. So thanks Al for sharing. I'm going to demonstrate how to install Paramiko using the steps that Al has shared on the GNS3 community. In this topology I've got an Ubuntu docker container which I've configured to use DHCP. That's now booted and got an IP address from the NAT cloud. So as an example the Ubuntu client can ping google.com. The Cisco switch in this topology has just booted but has no configuration on it. So I'll demonstrate in a moment how to configure SSH on the switch and then we'll configure the Ubuntu client to use Paramiko and SSH to configure the switch. The module that I'm going to use for SSH is Paramiko. This is a Python implementation of the SSH version 2 protocol which provides both client and server functionality. You can find out more information about Paramiko on paramiko.org or docs.paramiko.org. I've written a script which I've linked below on github that imports Paramiko and uses SSH to connect to the Cisco switch and configure some options on the switch. We'll configure some loopback interfaces and then we'll run a loop to configure VLANs on the switch. So I'm hoping that this video and script help you configure network devices using SSH rather than just relying on telnet. In this example I'm using sublime text which is a great text editor. You can find out more about sublime text on their website sublimetext.com. Unfortunately no one pays me money to recommend these products. This is just stuff that I've found useful and you may be interested in knowing about as well. Ok so the first thing we need to do is install Paramiko and Python on this Ubuntu client. This Ubuntu client has just booted up, doesn't have any configuration apart from an IP address. So what I'll simply do here is follow the list of commands that Al has put on the GNS3 community and I'll reference the links below. So install Python, install some additional software, install pip. I'll use pip to install cryptography and then we'll use pip to install Paramiko. You simply need to wait for the processes to complete. So install Paramiko here as well and I'll upgrade pip while I'm here. So once again, Paramiko is now installed on this Ubuntu server. So follow these steps if you want to install Paramiko on your Ubuntu client. So that's the Ubuntu device configured. We now need to configure the switch for SSH. So to set up a SSH on the switch the first thing we need to do is configure a hostname which we've done already. Then we're going to specify a domain name which in this case I'm going to call CCIE Python.com. Then we're going to generate some keys so cryptic key generate RSA. I'll use 1024 as the number of bits. So that's been done. I'll specify an enable password of cisco and in this example I'll configure a username of david password of cisco and give david level 15 privileges on the vty lines. I'll use the login local command and transport input all. So SSH is now configured on the switch. what we can do now is have a look at our python script. So we're going to import Paramiko, we're also going to import a time you may want to add some delays in your script and that's what sleep allows you to do. So I'm sleeping one second before I'm outputting the session when I'm creating the VLANs on the switch. I'm also adding a half a second delay to the loop otherwise I found that that VLANs weren't created successfully. So import Paramiko, import time I'm specifying the IP address of the switch that I'm going to SSH to. Discounted link to course here: https://goo.gl/ntqu3G

NaCl: A New Crypto Library [ShmooCon 2015]
 
51:53
Daniel J. Bernstein and Tanja Lange NaCl (pronounced "salt") is a new easy-to-use high-speed software library for encryption, decryption, signatures, etc. NaCl's goal is to provide all of the core operations needed to build higher-level cryptographic tools. Of course, other libraries already exist for these core operations, but NaCl improves security, improves usability, and improves speed. We'll explain how the design and implementation of NaCl avoid various types of cryptographic disasters suffered by previous cryptographic libraries such as OpenSSL. This talk also presents TweetNaCl, a self-contained public-domain C library which reimplements the NaCl library in just 100 tweets. See https://twitter.com/tweetnacl. We're researchers in applied cryptography working on making secure crypto more usable and on eliminating bad crypto. This includes us sometimes breaking bad crypto but most of the time our work is constructive. We're the core NaCl development team, along with Peter Schwabe. We've designed several cryptosystems, including Salsa20, Poly1305, Curve25519, and Ed25519. These cryptosystems are designed for security, robustness, performance, and ease of implementation without data-dependent branches and without data-dependent array indices. We use these functions in NaCl to make our lives easier and the software better. We've done some other things in crypto as well.

Network Security - Advanced Encryption Standard
 
09:22
Fundamentals of Computer Network Security This specialization in intended for IT professionals, computer programmers, managers, IT security professionals who like to move up ladder, who are seeking to develop network system security skills. Through four courses, we will cover the Design and Analyze Secure Networked Systems, Develop Secure Programs with Basic Cryptography and Crypto API, Hacking and Patching Web Applications, Perform Penetration Testing, and Secure Networked Systems with Firewall and IDS, which will prepare you to perform tasks as Cyber Security Engineer, IT Security Analyst, and Cyber Security Analyst. course 2 Basic Cryptography and Programming with Crypto API: About this course: In this MOOC, we will learn the basic concepts and principles of cryptography, apply basic cryptoanalysis to decrypt messages encrypted with mono-alphabetic substitution cipher, and discuss the strongest encryption technique of the one-time-pad and related quantum key distribution systems. We will also learn the efficient symmetric key cryptography algorithms for encrypting data, discuss the DES and AES standards, study the criteria for selecting AES standard, present the block cipher operating modes and discuss how they can prevent and detect the block swapping attacks, and examine how to defend against replay attacks. We will learn the Diffie-Hellman Symmetric Key Exchange Protocol to generate a symmetric key for two parties to communicate over insecure channel. We will learn the modular arithmetic and the Euler Totient Theorem to appreciate the RSA Asymmetric Crypto Algorithm, and use OpenSSL utility to realize the basic operations of RSA Crypto Algorithm. Armed with these knowledge, we learn how to use PHP Crypto API to write secure programs for encrypting and decrypting documents and for signing and verify documents. We then apply these techniques to enhance the registration process of a web site which ensures the account created is actually requested by the owner of the email account. Module 2 - Symmetric Key Cryptography In this module we present the basic mechanism of symmetric key crytography algorithms, discuss the DES and AES standard, describe the criteria for selecting AES standard, present the block cipher operating modes and discuss how the block swapping attacks and replay attacks can be prevented and detected. Learning Objectives • Understand the criteria for selecting crypto algorithms • Perform cryptoanalysis on simple ciphers • Select operating modes for symmetric encryption and to prevent block swapping and replay attacks • Understand DES and AES standards and their buildig blocks Subscribe at: https://www.coursera.org

Eyeline Crypto Trading - Official Presentation
 
10:55
COMING SOON! Email Chad: craigs1669 @ gmail dot com / +1 773- 829 -0737 It is important to understand that in an affiliate plan that offers a crypto trading package, the money that comes in can go towards trading or towards operations and commissions; however, the same money can’t go into both. We understand this with Eyeline Trading and want to be as transparent as possible. 50% of all trading packages go towards operations and commissions, and 50% goes directly into your trading account! BTC Trading Packages: You make up to .66% per day of all the money that goes into your trading account for 365 days. After the 365 days, your package expires, and you get your original balance back plus all the profits you have earned for 365 days. Example on a $40 package (approximately .00555 BTC), $20 (approximately .00275 BTC) goes towards the trading package and $20 (approximately .00275 BTC) goes towards operations and commissions. So once your package starts paying out, you would earn approximately 13 cents per day for 365 days or approximately $48 (approximately .0066 BTC). And then at the end of the contract, you would also get your $20 that was in your trading account back for a total of $68 (approximately .009 BTC). (NOTE: In this example, I am using dollars; this would actually be in BTC as we do not take payment in dollars, or payout in dollars. This was just to try to make it as easy as possible to understand. If BTC goes down, your profits would be less. And if BTC goes up your profits would be more.)

PlayFair Cipher Encryption & Decryption | Polygraphic Substitution Cipher
 
10:47
PlayFair cipher is a polygram or polygraphic cipher which means it operates on block of characters (2 characters in this case) instead of single characters. Polygram or Polygraphic ciphers work with block of characters rather than single character itself. In this video tutorial we will understand the concept, encryption and decryption process of Playfair Cipher. Playfair Cipher operates on block of 2 characters each during encryption and decryption process. In this video tutorial we study the basic principles of Network security and also see the concept of Cryptography by understanding a basic example. Principles of Network Security to be discussed in this video are as follows: Confidentiality Authentication Integrity Non-repudiation Access Control Availability We will also learn the concept of Cryptography in this tutorial. Here's the definition of Cryptography: Cryptography is the art of achieving security by encoding messages to make them non-readable This video is a continuation of the previous video so make sure you check that video as well so that you get to know some basics of Network security.
