This is part 11 of the Blockchain tutorial explaining how the generate a public private key using Elliptic Curve. 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.

This video demonstrate the process of image encryption using elliptical curve cryptography. The complete code for it is available at https://free-thesis.com/product/image-encryption-decryption-using-ecc/. This is the code which simulates the encryption and decryption of an image using random and private keys in MATLAB. The elliptic curve cryptography is applied to achieve the security of any image before transmitting it to some one so that no other can see the data hidden in the image. At the receiver end the destined user will already have the decryption key used for this. If key is altered, image will not be decrypted.

Through the years, Java has become much more than just a programming language. It's also an enterprise platform for JEE application development. However, at some level, security and cryptography are easy to get wrong. Most of the time, we don't care which algorithms—SHA-256 or SHA-512, RSA or ECC, AES-128 or AES-256, padding schemes, iteration number, key sizes—are or aren't ideal for encryption, or if a poor choice could benefit attackers. In this technical session, we won't use complex math, and most of the concepts will be illustrated with source code, as we explore: - Broken cryptography - Libraries available for development - Hashing passwords and what people have been doing wrong - Usage of digital signatures - Protecting local data - How to properly exchange encryption keys - Securely sending data over the network - Preventing illegal tampering on client/server applications - SSL best practices - Cryptography in our daily basis

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/

Do you feel cryptographic libraries are just thrown over the fence for us developers and security professionals to understand and pray its used securely? Java Cryptography Architecture is one such famously used the library, laden by ambiguous documentation, over-abundance of algorithmic and key material choices, insecure defaults, and poor architectural choices. All these collectively make it highly probable to make an unfortunate choice and lands us with a flawed cryptographic system. In this session, learn how to securely use each of the Java Cryptography Architecture’s primitives (Random Number Generators, Encryption/Decryption algorithms, HMACs, digital signatures etc.) using real-world code examples to highlight areas that require careful attention and difficult choices. Examine both good and flawed implementations, and learn how to spot mistakes. Then learn how to future-proof the crypto in your applications.

Transactions on a blockchain have to be signed with a private key. This makes sure that people can only spend coins if they have the private key of their wallet. In this video we will refactor our Javascript blockchain so that it will only accept signed transactions. We'll use the secp256k1 elliptic curve to generate a keypair. The same algorithm used in Bitcoin. But you can use other algorithms as well. 🤲 Source code Available on GitHub: https://github.com/SavjeeTutorials/SavjeeCoin 💰 Buy Bitcoin, Ethereum, Litecoin, ..
