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.

Vídeo original: https://youtu.be/iB3HcPgm_FI 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/blackboard1... Here's the private key and the link to the public address that we use. Do you know why it is famous?
