IOTA tutorial 21: CryptoJS
 
03:40
If you like this video and want to support me, go this page for my donation crypto addresses: https://www.youtube.com/c/mobilefish/about This is part 21 of the IOTA tutorial. In this video series different topics will be explained which will help you to understand IOTA. It is recommended to watch each video sequentially as I may refer to certain IOTA topics explained earlier. The main objective of this video is to provide you with some basic knowledge about CryptoJS. CryptoJS is a collection of standard and secure cryptographic algorithms implemented in JavaScript using best practices and patterns. They are fast and they have a consistent and simple interface. Jeff Mott is the original author of the crypto-js library which was one of the many code projects hosted by the Google Code Project Hosting Service. The Google Code Project Hosting Service was turned down in early 2016. The many code projects can still be found at the Google Code Archive. https://code.google.com/archive/ Jeff Mott’s CryptoJS library can be found at: https://code.google.com/archive/p/crypto-js/ The CryptoJS last version is v3.1.2 and last updated in Jan 15, 2013. See: https://code.google.com/archive/p/crypto-js/downloads How to use the CryptoJS functions, see: https://code.google.com/archive/p/crypto-js https://code.google.com/archive/p/crypto-js/wikis/QuickStartGuide_v3beta.wiki It seems that this library is not maintained by Jeff Mott anymore. Jeff Mott’s CryptoJS library has been forked by several developers and can be found at Github: https://github.com/brix/crypto-js https://github.com/sytelus/CryptoJS https://github.com/gwjjeff/cryptojs The fork created by Evan Vosberg (brix/crypto-js) is still maintained. The (Brix) CryptoJS library can be found at: https://github.com/brix/crypto-js An npm module has been created for the (Brix) CryptoJS library which can be found at: https://www.npmjs.com/package/crypto-js To include all CryptoJS libraries in JavaScript: var CryptoJS = require(“crypto-js”); The (Brix) CryptoJS library is also available in the free and open source web front-end resource Content Delivery Network (CDN): https://cdnjs.com/libraries/crypto-js The (Brix) CryptoJS library are used by several Distributed Ledger projects, such as: - IOTA (in the iota.lib.js library) https://github.com/iotaledger/iota.lib.js/blob/master/package.json - Ethereum (in the web3js library) https://github.com/ethereum/web3.js/blob/develop/package.json Understanding how the CryptoJS library works would be beneficial to you if you are an IOTA or Ethereum front-end developer. The CryptoJS library has no asymmetric key algorithms, such as RSA. More information how to use CryptoJS, see: https://code.google.com/archive/p/crypto-js/wikis/QuickStartGuide_v3beta.wiki https://github.com/brix/crypto-js https://www.davidebarranca.com/2012/10/crypto-js-tutorial-cryptography-for-dummies/ Check out all my other IOTA tutorial videos: https://www.youtube.com/playlist?list=PLmL13yqb6OxdIf6CQMHf7hUcDZBbxHyza Subscribe to my YouTube channel: https://www.youtube.com/channel/UCG5_CT_KjexxjbgNE4lVGkg?sub_confirmation=1 The presentation used in this video tutorial can be found at: https://www.mobilefish.com/developer/iota/iota_quickguide_tutorial.html #mobilefish #howto #iota

Trading cryptocurrencies, forex, commodities stocks and more using node.js
 
25:02
Description: The aim of the talk is to show what i have learnt and the libraries and tools i have developed over the last couple years after getting into trading bitcoin and ethereum, which turned out later into trading all sorts of things based on technical analysis and a bit of flaky statistics. I'm really bad at making graphs and charts and what not, so expect some hands on approach, the talk should cover the very basics of trading and then how to use trading APIs to actually buy and sell stuff online directly from your command line. About me: The first time i programmed javascript was twenty years ago and since them i have played around with pretty much all the interesting programming languages i have found in front of me just to discover in 2011 i would actually end up doing everything again using only node.js. During this long journey i have worked on backend and frontend applications, interactive games, multiplayer applications, and whatnot. The last few years my big interest turned to be blockchain, cryptocurrencies and trading. After moving to London nearly seven years ago i worked for a few years in a very nice design studio and then later left to create my own little technology company where all those crazy experiments happen.

Cryptography for JavaScript Developers - Nakov @ JS.Talks() 2018
 
01:12:44
Title: Cryptography for JavaScript Developers Speaker: Svetlin Nakov, PhD Conference: js.talks() 2018 Most developers believe they know cryptography, just because they store their passwords hashed instead of in plaintext and because have once configured SSL. In this talk the speaker fills the gaps by explaining some cryptographic concepts with examples in JavaScript. The talk covers: - Hashes, HMAC and key derivation functions (Scrypt, Argon2) with examples in JavaScript - Encrypting passwords: from plain text to Argon2 - Symmetric encryption at the client-side: AES, block modes, CTR mode, KDF, HMAC, examples in JavaScript - Digital signatures, ECC, ECDSA, EdDSA, signing messages, verifying signatures, examples in JavaScript - Why client-side JavaScript cryptography might not be safe? Man-in-the-browser attacks, Cross-Site Scripting (XSS) / JavaScript injection, etc. More info, slides and video: http://www.nakov.com/blog/2018/11/18/cryptography-for-javascript-developers-nakov-js-talks-2018/

Hashing Passwords | Node Authentication Tutorial – Part 3
 
08:32
🚀Support Chris Courses with Patreon: https://www.patreon.com/chriscourses 🖥Professional Web Development Services from Chris: https://resovere.com/ Learn the basics behind hashing users' passwords and why it is so very important to do this within any password related app. When it comes to securing your users' passwords, it's integral, no, absolutely necessary to hash your users' passwords before storing them in a database. Hashing is the process of scrambling up a user's password into a long string of characters that's undecipherable. The interesting thing about hashing: once you put the password in the hasher, there's no way to convert it back to its original form (at least from a mathematical standpoint). This helps ensure that your users' passwords are unreadable in the off chance someone happens to stumble upon the data in your database. Code along with me as I demonstrate how to implement hashing functionality into our user based node app. bcrypt npm link: https://www.npmjs.com/package/bcrypt Video Git Repo (starts at part 1): ------------------------------------------------ https://github.com/christopher4lis/express-cc Node Authentication Process: ------------------------------------------ // Add our boilerplate // 1.x Git clone express-cc repo // 2.x Run yarn / npm install // Create a new user in the database // 1.x Create a form within a view // 2.x Create route that'll process the form's post request // 3.x Create a database connection using .env file // 4.x Grab form input and insert into database // 5.x Add express-validation package // 6.x Validate user input on backend // 7.x Validate user input on frontend // 8.x Hash our user's password // 9.x Store user in database // Login user (update user session, return auth cookie) // 1. Install passport // 2. Configure passport with local strategy // Protect routes and only permit entry with authorization cookie // Create logout button // Create login page Video Timeline: ----------------------------- 00:50 - Why storing passwords in plain text is bad 01:36 - What is hashing? 02:35 - How to hash our users' passwords 03:05 - What is bcrypt? 06:01 - What is a salt? 07:08 - Testing out our hashing implementation To be continued...

Asymmetric Encryption and Signing with Public Private Keys
 
23:08
Bob and Alice will only get you so far. Article at https://coolaj86.com/articles/asymmetric-public--private-key-encryption-in-node-js/ Without getting deep into math, I paint a picture of specifically how RSA encryption works, it's connection with AES, and how HTTPS and GPG use both. I also show examples using the OpenSSL commandline tools and ursa in node.js. It's still pretty high-level, but with sprinkled with some practical details and understanding you may not have had before. Examples with OpenSSL Node.js

TensorFlow.js - Serve deep learning models with Node.js and Express
 
08:27
To build deep learning applications that run in the browser, we need a way to host these applications and a way to host the models. So then, really, we just a way to serve static files. Let's go through the process of getting a web server set up to host deep learning web applications and serve TensorFlow.js models with Express for Node.js. Enter Express for Node.js. Express is a minimalist web framework, very similar to Flask, but is for Node.js, not Python. If you’re not already familiar with Node.js, it is an open-source run-time environment that executes Javascript code on the server-side.

Learn TensorFlow.js - Deep Learning and Neural Networks with JavaScript
 
01:19:37
This full course introduces the concept of client-side artificial neural networks. We will learn how to deploy and run models along with full deep learning applications in the browser! To implement this cool capability, we’ll be using TensorFlow.js (TFJS), TensorFlow’s JavaScript library. By the end of this video tutorial, you will have built and deployed a web application that runs a neural network in the browser to classify images! To get there, we'll learn about client-server deep learning architectures, converting Keras models to TFJS models, serving models with Node.js, tensor operations, and more!

N-API - Next Generation Node API for Native Modules
 
32:38
N-API - Next Generation Node API for Native Modules [I] - Michael Dawson, IBM & Arunesh Chandra, Microsoft Until now, native module (add-ons) maintainers have had to recompile for each Node.js release as well as potentially updating their code to cope with the rapid pace of changes in the v8 APIs. The community API working group has been developing the N-API (Node-API) as a follow on to Nan to help solve this problem and insulate modules from changes in the v8 APIs. By targeting the new API, modules will be able support a wide variety of Node.js releases without needing recompilation or abstraction layers such as Nan - reducing deployment time and maintenance effort for both module developers and Node.js end users. With an initial version of the API slated to be part of Node version 8 as an experimental feature, it is a good time to come learn about the shape and usage of the new API from those working to implement it. About Arunesh Chandra Sr. Program Manger @ChakraCore, Microsoft Arunesh Chandra is working on growing Node.js by extending it to use the ChakraCore engine. He is also working on supporting fresh ideas in the community like VM Neutrality for Node.js and bringing innovative diagnostic tooling like Time-Travel Debugging to Node developers. Michael Dawson IBM Senior Software Developer Ottawa, Ontario Twitter Tweet Michael Dawson is an active contributor to Node.js and a CTC member. He contributes to a broad range of community efforts including platform support, build infrastructure, N-API, LTS as well as tools to help the community achieve quality with speed (ex: ci jobs, benchmarking and code coverage reporting). Within IBM he leads the Node.js team driving IBM’s Node.js runtime deliveries and their contributions to Node.js and v8 within the Node and google communities. Past experience includes building IBM's Java runtime, building and operating client facing e-commerce applications, building PKI and symmetric based crypto solutions as well as a number of varied consulting engagements. In his spare time he uses Node.js to automate his home and life for fun.
