Cooking with Cryptography by Fraser Tweedale
 
35:02
The ``cryptography`` library emerged in 2014 with the goal of becoming Python's "cryptographic standard library". It is designed to be easy to use but flexible, exposing a *recipes* layer for common use cases, and a *hazmat* layer that provides crypto primitives but demands users know what they're doing in order to use them properly. This talk will explain the motivations and goals of the ``cryptography`` library, take a tour of its features and discuss its implementation. ``cryptography`` will be compared to some other popular and emerging crypto libraries. Finally, we will examine some real-world use of the library. Audience members should have a passing familiarity with cryptography (e.g. know the differences between hashing and encryption, or public key and private key crypto) to get the most out of this talk. PyCon Australia is the national conference for users of the Python Programming Language. In 2015, we're heading to Brisbane to bring together students, enthusiasts, and professionals with a love of Python from around Australia, and all around the World. July 31-August 4, Brisbane, Queensland, Australia

Jose Ortega - Python Security & Cryptography [EuroPython 2015] [22 July 2015] [Bilbao, Euskadi, Spain] The talk would aim to introduce cryptography and security from the developer point of view, showing ways to encrypt information with Python scripts and more sensitive information in web applications using django. I will introduce to security in python ,showing some libraries that allow encryption and decryption like PyCrypto or M2Crypto,comparing theses libraries with the cryptography module.At the same time,I will show the main ciphers and hashing algorithms used in these libraries like AES,DES,RSA and some examples illustrating each case.I wil show other techniques like steganography for hiding information in files(images,documents,programs) with some libraries like Stepic or ezPyCrypto. Finally,I will comment OWASP Python Security Project where we can find some useful practices and secure coding guidelines for detecting potential security vulnerabilities in our applications like SQL injection or Cross-site scripting. **Slides** [https://speakerdeck.com/jmortega/python-cryptography-and-security][1] [1]: https://speakerdeck.com/jmortega/python-cryptography-and-security

The State of Crypto in Python
 
39:33
Python has a complex past with cryptography. There are half a dozen major frameworks built on at least three separate C implementations, each with their own strengths and weaknesses and in various states of maintenance. In our development of an open source key management system for OpenStack (Barbican), our team has spent time investigating the major options. This presentation will review the current state of the art and discuss the future of crypto in Python including a new library being developed by a group of Python devs aimed at unifying and expanding the support for modern crypto in the Python ecosystem. Additional advice will be provided for developers and security professional around which libraries provide the best support for an application particular crypto needs.

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.)

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

How To Get The 30 Day Pricing for a Cryptocurrency in Sheets Using Python (2018)

It basically pulls the coin list data from our google spreadsheet. Then grabs the last 30 days of prices from cryptocompare. It then places the 30 days of pricing into a big sheet. Then we do a sparkline function to tabulate that list of data in google sheets and finally do a Vlookup in the main tab to access the data.
