High Capacity PHP Random String Generator Function Programming Tutorial
Lesson Code: http://www.developphp.com/video/PHP/Random-String-Generator-PHP-Function-Programming-Tutorial Learn to program a high capacity PHP random string generator with dynamic length parameter. We demonstrate how to then make your script modular in order for it to be reusable, external and dynamic. Splitting (str_split) any string gives you an array from that string, then you can pluck out elements of that array (array_rand) within a for loop in order to return a randomly generated string of characters of any length.

JMS240: Secure User Authenticaion and Cryptographically Secure Tokens in PHP
A common problem in PHP is creating cryptographically secure tokens for user authentication. Think "remember me" and password reset features. Functions like rand(), mt_rand() and uniqid() simply aren't enough. And, without "resource-improbable" tokens... it's only a matter of time for a hacker to break your authentication and get int your application. Fortunately, PHP 5.6 and 7 have added the necessary functions for us to creating cryptographically secure tokens, prevent timing attacks and mitigate data hacks. That latest in all this in this episode. Show notes and sources: https://www.johnmorrisshow.com/240 #php #webdev

Black Hat USA 2012 - PRNG Pwning Random Number Generators (In PHP Applications)
By: George Argyros & Aggelos Kiayias We present a number of novel, practical, techniques for exploiting randomness vulnerabilities in PHP applications. We focus on the predictability of password reset tokens and demonstrate how an attacker can take over user accounts in a web application via predicting the PHP core randomness generators. Our suite of new techniques and tools go far beyond previously known attacks (e.g. Kamkar and Esser) and can be used to mount attacks against all PRNG of the PHP core system even when it is hardened with the Suhosin extension. Using them we demonstrate how to create practical attacks for a number of very popular PHP applications (including Mediawiki, Gallery, osCommerce and Joomla) that result in the complete take over of arbitrary user accounts. While our techniques are designed for the PHP language, the principles behind ]them are independent of PHP and readily apply to any system that utilizes weak randomness generators or low entropy sources. We will also release tools that assist in the exploitation of randomness vulnerabilities and exploits for some vulnerable applications.

I Forgot Your Password: Randomness Attacks Against PHP Applications
This video is part of the Infosec Video Collection at SecurityTube.net: http://www.securitytube.net I Forgot Your Password: Randomness Attacks Against PHP Applications Slide : - https://www.usenix.org/system/files/conference/usenixsecurity12/sec12-final218.pdf We provide a number of practical techniques and algorithms for exploiting randomness vulnerabilities in PHP applications.We focus on the predictability of password reset tokens and demonstrate how an attacker can take over user accounts in a web application via predicting or algorithmically derandomizing the PHP core randomness generators. While our techniques are designed for the PHP language, the principles behind our techniques and our algorithms are independent of PHP and can readily apply to any system that utilizes weak randomness generators or low entropy sources. Our results include: algorithms that reduce the entropy of time variables, identifying and exploiting vulnerabilities of the PHP system that enable the recovery or reconstruction of PRNG seeds, an experimental analysis of the Hstad-Shamir framework for breaking truncated linear variables, an optimized online Gaussian solver for large sparse linear systems, and an algorithm for recovering the state of the Mersenne twister generator from any level of truncation. We demonstrate the gravity of our attacks via a number of case studies. Specifically, we show that a number of current widely used web applications can be broken using our techniques including Mediawiki, Joomla, Gallery, osCommerce and others.

DEF CON 22 - Dan Kaminsky - Secure Random by Default
Secure Random By Default Dan Kaminsky Chief Scientist, White Ops As a general rule in security, we have learned that the best way to achieve security is to enable it by default. However, across operating systems and languages, random number generation is always exposed via two separate and most assuredly unequal APIs -- insecure and default, and secure but obscure. Why not fix this? Why not make JavaScript and PHP and Java and Python and even libc rand() return strong entropy? What are the issues stopping us? Should we just shell back to /dev/urandom, or is there merit to userspace entropy gathering? How does fork() and virtualization impact the question? What of performance, and memory consumption, and headless machines? Turns out the above questions are not actually rhetorical. Just because a change might be a good idea doesn't mean it's a simple one. This will be a deep dive, but one that I believe will actually yield a fix for the repeated *real world* failures of random number generation systems. Dan Kaminsky has been a noted security researcher for over a decade, and has spent his career advising Fortune 500 companies such as Cisco, Avaya, and Microsoft.Dan spent three years working with Microsoft on their Vista, Server 2008, and Windows 7 releases. Dan is best known for his work finding a critical flaw in the Internet’s Domain Name System (DNS), and for leading what became the largest synchronized fix to the Internet’s infrastructure of all time. Of the seven Recovery Key Shareholders who possess the ability to restore the DNS root keys, Dan is the American representative. Dan is presently developing systems to reduce the cost and complexity of securing critical infrastructure.

Cryptography, Perfect Secrecy and One Time Pads | Two Minute Papers #25
Cryptography helps us to communicate securely with someone in the presence of third parties. We use this when we do for instance, online banking or even as mundane tasks as reading our gmail. In this episode, we review some cipher techniques such as the Caesar cipher, rot13, and as we find out how easy they are to break, we transition to the only known technique to yield perfect secrecy: one time pads. Are they practical enough for everyday use? How do our findings relate to extraterrestrial communications? Both questions get answered in the video. Additional comment: "In modern certification cryptanalysis, if a cipher output can be distinguished from a PRF (pseudo random functions), it's enough to deem it broken." - Source: https://twitter.com/cryptoland/status/666721478675668993 ______________________ The paper "Cipher printing telegraph systems: For secret wire and radio telegraphic communications" is available here: http://math.boisestate.edu/~liljanab/Math509Spring10/vernam.pdf You can try encrypting your own messages on these websites: http://practicalcryptography.com/ciphers/caesar-cipher/ http://rot13.com/index.php http://www.braingle.com/brainteasers/codes/onetimepad.php Subscribe if you would like to see more of these! - http://www.youtube.com/subscription_center?add_user=keeroyz The thumbnail background was created by Adam Foster (CC BY 2.0) - https://flic.kr/p/b99vsi Splash screen/thumbnail design: Felícia Fehér - http://felicia.hu Károly Zsolnai-Fehér's links: Patreon → https://www.patreon.com/TwoMinutePapers Facebook → https://www.facebook.com/TwoMinutePapers/ Twitter → https://twitter.com/karoly_zsolnai Web → https://cg.tuwien.ac.at/~zsolnai/

How do we know our PRNGs work properly? (33c3)
https://media.ccc.de/v/33c3-8099-how_do_we_know_our_prngs_work_properly Pseudo-random number generators (PRNGs) are critical pieces of security infrastructure. Yet, PRNGs are surprisingly difficult to design, implement, and debug. The PRNG vulnerability that we recently found in GnuPG/Libgcrypt (CVE-2016-6313) survived 18 years of service and several expert audits. In this presentation, we not only describe the details of the flaw but, based on our research, explain why the current state of PRNG implementation and quality assurance downright provokes incidents. We also present a PRNG analysis method that we developed and give specific recommendations to implementors of software producing or consuming pseudo-random numbers to ensure correctness.

(Source code on request. UPDATE: See below) Made an encryption scheme that creates a square (padding random bytes if necessary) and shifts a square based on the password. Given the same password, it will perform the same shifts. Decryption uses the same algorithm but performs the actions backwards. Another version (shown second, starting at 0:53) also does character substitution. This basically adds up the values of each character of the password and each character of the data, modulus the length of the character set of course. After that it still performs shifting. It's not going to be used for anything at all ("rolling your own" is always an extremely bad idea in cryptography, I know that very well), I just enjoyed creating it. Just shifting the square around seems to give a pretty random outcome, and with character substitution you really can't tell what the original was. The algorithm also includes an extremely simple key derivation function which obfuscates the key input for a more random looking output (though the key needs not be fixed-length). It only accepts ASCII input, no accents or euro symbols or anything outside 32-127. It's not meant to be really used anyway. Again, source available on request. Note that I can't comment because then I'd need to make a Google+ profile, but I will read comments (typically within 24 hours, assuming I get an email notification) and simply edit the description to include a link. SOURCE CODE Update June 2018: Wow, I had no idea there were comments on this video at all. Everyone has been asking for years! Sorry! http://lucb1e.com/rp/php/horrible-encryption-square.php I have to warn you, it's not super easy to use. You need to have PHP installed on the command line (Ubuntu/Debian/Mint: apt install php-cli) and run it as shown in the video. To change whether it does substitution, see the third line of the file.

Why not squares? Or asymmetrical blobby shapes? In 36 B.C., the Roman scholar Marcus Terentius Varro wrote about two of the leading theories of the day. First: bees have six legs, so they must obviously prefer six-sided shapes. But that charming piece of numerology did not fool the geometers of day. They provided a second theory: Hexagons are the most efficient shape. Bees use wax to build the honeycombs -- and producing that wax expends bee energy. The ideal honeycomb structure is one that minimizes the amount of wax needed, while maximizing storage -- and the hexagonal structure does this best.
