Cryptography is a complex and confusing subject. In this talk you will learn about the core components of cryptography used in software development: securing data with encryption, ensuring data integrity with hashes and digital signatures, and protecting passwords with key derivation functions. While learning how to use these components, you will also learn the best practices that drive strong cryptography. This talk won’t make you a cryptography expert but it will give you the knowledge necessary to use cryptography properly. No prior knowledge of cryptography is required for this presentation.

Intro to Cryptography in Python "Cryptography. Cryptography is an actively developed library that provides cryptographic recipes and primitives. It supports Python 2.6-2.7, Python 3.3+ and PyPy. ... The recipes layer provides simple API for proper symmetric encryption and the hazmat layer provides low-level cryptographic primitives." - https://docs.python-guide.org/scenarios/crypto/

XOR ciphers take advantage of Ascii encoding and basic bit switching operations. They are extremely fast, but not particularly secure when used alone, without a key exchange algorithm. XOR ciphers make up much of the basis of how modern encryption works.

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.

I was bored and browsing youtube videos earlier and I watched a brief video on cryptography and decided to write a program to implement one of the ideas I saw. Dashed this out in Python to encrypt/decrypt text. It uses a private key and is relatively secure. Just a bit of fun for any of the nerds out there

In this vid we'll complete the encryption side of our implementation of AES. I've decided not to go though decryption, which is much the same type of logic in reverse, and with the opposite look-up tables. If you actually have to include AES in your programs, use assembly or AES intrinsics. Our implementation is not secure, and it's very slow. Modern CPU's have an instruction set called the AES Instruction Set, which makes this whole task a lot easier, and a lot faster. The babies you can hear at point are my sweet little nieces. I live with my bro and his gf. They've just had twins. They sound like they're being attacked by an elephant, but they are just hungry. They quieten down when their ma feeds them. I hope this vid series was helpful for folks studying the algorithm. There's very few examples of exactly how to code this thing. Anywho, I really wanted to make a good go of it. Well here it is! Now we can look at something completely different! Well probably not that different...?

Welcome to part four in our series on Elliptic Curve Cryptography. I this episode we dive into the development of the public key. In just 44 lines of code, with no special functions or imports, we produce the elliptic curve public key for use in Bitcoin. Better still, we walk you through it line by line, constant by constant. Nothing makes the process clearer and easier to understand than seeing it in straight forward code. If you've been wondering about the secp256k1 (arguably the most important piece of code in Bitcoin), well then this is the video for you. This is part 4 of our upcoming series on Elliptic Curves. Because of such strong requests, even though this is part 4, it is the first one we are releasing. In the next few weeks we will release the rest of the series. Enjoy. Here's the link to our Python code (Python 2.7.6): https://github.com/wobine/blackboard101/blob/master/EllipticCurvesPart4-PrivateKeyToPublicKey.py Here's the private key and the link to the public address that we use.
