Fast random number generation in Python and NumPy
 
39:32
Bernardt Duvenhage https://za.pycon.org/talks/53-fast-random-number-generation-in-python-and-numpy/ A fast Random Number Generator (RNG) is key to doing Monte Carlo simulations, efficiently initialising machine learning models, shuffling long sequences of numbers and many tasks in scientific computing. CPython and NumPy use implementations of the Mersenne Twister RNG and rejection sampling to generate random numbers in an interval. The NumPy implementation trades more samples for cheaper division by a power of two. The implementation is very efficient when the random interval is a power of two, but on average generate many more samples compared to the GNU C or Java algorithms. The Python RNG uses an algorithm similar to GNU C. A recent paper by Daniel Lemire (https://arxiv.org/abs/1805.10941) discusses an efficient division light method to generate uniform random numbers in an interval. This method is apparently used in the Go language. On 64-bit platforms there are also fast alternative RNGs that perform comparatively on statistical examinations passing tests like BigCrush. The splitmix64 (part of the standard Java API) and lehmer64 RNGs, for example, require approximately 1.5 cycles to generate 32 random bits (without using SIMD) while the 32-bit Mersenne Twister requires approximately 10 cycles per 32 bits. This talk will discuss the inclusion of Lemire's method in NumPy as an alternative to the current rejection sampling implementation. My implementation results in a 2x - 3x improvement in the performance of generating a sequence of random numbers. Using splitmix64 or lehmer64 RNGs in NumPy instead of the Mersenne Twister results in a further 2x performance improvement. The random module in Python does not do the rejection sampling in C like NumPy does. Much of the time to get a random number is therefore spent in the Python code. This talk will also discuss a fast random Python module that implements Lemire's method instead of the current rejection sampling, provides alternative RNGs and moves more of the code into C. I'm considering doing pull requests for both the NumPy modification and the Python fast random module and will present a detailed analysis of the proposed modifications. pyconza2018 python

Python Tips and Tricks:  Every Python Programmer Must Know
 
05:34
Here are some cool tips and tricks which is used while making a project or program. 10. Adding 2 list : for this you just have to create 2 list and then combine them in 2 variables. i.e. a=[1,2,3] b=[4,5,6] then c=a+b. Now c can hold 2 list. 9: Calendar: In this trick you can print calendar according to calendar format like import calendar then print calendar.month(2017,1) you can also pass variable to it according to your format. 8: Swap: In other languages you have to write multiple lines of code for it but in Python you can just do it by single line i.e a,b=b,a that's the beauty of python. 7: List: In python you can convert any string into list by using list function i.e a='abcd' then a=list(a). If your list contains integer values then just convert it by using str() function i.e a=123 then a=str(a) now you can convert it into list. 6: Join: You can join list elements by using join function i.e. ''.join(msg) also if you pass any value within '' then it join with all elements. 5: Date Time: This is the essential thing for programmer to show it any project or program just import datetime module and call the function and print it (by watching the video) also you can change the format of it %d for date, %m for month, %y for year, %I for hour, %M for minute, %s for second, %p for 12 hour. 4. Random : using random function is essential in making games, cryptography,projects etc , in python import random module and select your random value via random.choice(variable). You can also select list or any type of value. 3: Color : A program can become more attractive if it has a beautiful color in it. Just import os module and put os.system('color A') and set color according to you. Color code in os are: 0: black 1: blue 2: green 3: aqua 4: red 5: purple 6: yellow 7:white 8: gray 9: light blue A: light green B: light aqua C: light red D: light purple E: light yellow F: Bright white 2: Compress: Sometimes you have to compress your messages or values in your program, by python you can do it eaisly, Just import zlib module and pass your message in zlib.compress(msg), it compress your msg, to decompress just use zlib.decompress(msg) to decompress it. 1: Message Box: To make a program user friendly, this is very useful, just import ctypes and write ctypes.windll.user32.MessageBoxA(0,'Your Message','Message title',0) here 0 is for ok button. You can also use tkinter but i like this though. So guys that's all in this video. Hope you like it . Thumbs up if you like it and subscribe to get more new stuff.

Bitcoin 101 - Elliptic Curve Cryptography - Part 4 - Generating the Public Key (in Python)
 
21:22
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.

Startup: High-quality Random Number Generator
 
10:03
In this video Luka Matic explains why and how he designed and built a super duper random number generator that passes official regulatory (DIN, NIST, etc.) tests for randomness. Based on noise Zener diodes the circuit fills an SD card with files of up to 4 GB of really random data. On http://www.elektormagazine.com Luka writes: This Random Number Generator uses Zener diodes to generate avalanche noise signal, then differential amplifier (and a few analog filters) to eliminate deterministic effects. The noise signal is captured by ATTiny2313 and sent to an FAT32 SD card as a sequence of meaningless hex numbers. I tested random number sequences in MATLAB to check for randomness. I designed and produced a prototype PCB (that you can see on the elektormagazine website (https://www.elektormagazine.com/labs/random-number-generator-150116). This RNG is designed with cheap and ubiquitous components and still creates random sequences of good randomness. I tried all the methods that I know to analyze the random sequences. If you know more about mathematical methods for checking the randomness of the sequence, you could be interested to check yourself. I have the circuit schematics drawn on paper.

Random Python 03: Brute-forcing truncatable primes | Timelapse
 
03:02
Hi there! In this video I created a simple program which finds left or right truncatable primes. After watching the Numberphile video: https://www.youtube.com/watch?v=azL5ehbw_24 I decided to try and write a python script to find them. You can find the source code here: https://github.com/ionelaipatioaei/Random-Python/tree/master/Truncatable%20primes Music used in this video: 1.

To solve this problem, we’ve created “untwister:” an attack tool for breaking insecure random number generators and recovering the initial seed. We did all the hard math, so you don't have to! Random numbers are often used in security contexts for generating unique IDs, new passwords for resets, or cryptographic nonces. However, the built-in random number generators for most languages and frameworks are insecure, leaving applications open to a series of previously theoretical attacks. Lots of papers have been written on PRNG security, but there's still almost nothing practical you can use as a pentester to actually break live systems in the wild. This talk focuses on weaponizing what used to be theoretical into our tool: untwister. Let's finally put rand() to rest. DISCLAIMER: This video is intended for pentesting training purposes only.
