AES Encryption 5: Expand Keys and Encryption Flow
 
32:51
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...?

Jose Ortega - Python Security & Cryptography
 
38:50
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
How to Install Python SSL Wrapper M2Crypto on  ubuntu Linux
 
00:50
M2Crypto is a python wrapper for Secure Socket Layer (SSL) Protocol. M2Crypto is used by python developers for configuring the secure communication between client and server. M2Crypto is well formatted wrapper and uses all SSL related protocols/algorithms such as SA, DSA, DH, HMACs, message digests, symmetric ciphers etc. M2crypto was developed by Ng Pheng Siong, it is a powerful Python library.
