Presentation name: Russian GOST cryptography in and near OpenSSL Speaker: Belyavskiy Dmitry Description: There is a necessity to provide national cryptography in various applications. The presentation describes history, current state and future of Russian GOST support in OpenSSL and OpenSSL-based applications. Russian GOST support in OpenSSL is divided between modifications of OpenSSL itself and the engine (https://github.com/gost-engine/engine) implementing the low-level cryptographic primitives. The presentation describes the edge cases of using externally provided algorithms, problems of support of the national specifics in OpenSSL and adopting applications and standards to support national cryptography. The presentation contains history of the universal API for asymmetric cryptography in OpenSSL and provides some ideas about possible API development to make it more flexible. [ https://sched.co/Jcd9]

Bob and Alice will only get you so far. Article at https://coolaj86.com/articles/asymmetric-public--private-key-encryption-in-node-js/ Without getting deep into math, I paint a picture of specifically how RSA encryption works, it's connection with AES, and how HTTPS and GPG use both. I also show examples using the OpenSSL commandline tools and ursa in node.js. It's still pretty high-level, but with sprinkled with some practical details and understanding you may not have had before. Examples with OpenSSL Node.js

An Overview of the Linux Kernel Crypto Subsystem - Boris Brezillon, Free Electrons The Linux kernel has long provided cryptographic support for in-kernel users (like the network or storage stacks) and has been pushed to open these cryptographic capabities to user-space along the way. But what is exactly inside this subsystem, and how can it be used by kernel users? What is the official userspace interface exposing these features and what are non-upstream alternatives? When should we use a HW engine compared to a purely software based implementation? What's inside a crypto engine driver and what precautions should be taken when developing one? These are some of the questions we'll answer throughout this talk, after having given a short introduction to cryptographic algorithms. About Boris Brezillon Since 2014, Boris works at Free Electrons, a company offering development, consulting and training services to embedded Linux system developers worldwide. He has been working on embedded systems since 2008, mostly Linux on ARM. Boris has written and upstreamed a Linux kernel driver for the Marvell CESA cryptographic engine, he is the maintainer of the MTD NAND subsystem, and has contributed to support for Atmel and Allwinner ARM SoCs in the Linux kernel.

What is CRYPTOGRAPHIC ACCELERATOR? What does CRYPTOGRAPHIC ACCELERATOR mean? CRYPTOGRAPHIC ACCELERATOR meaning - CRYPTOGRAPHIC ACCELERATOR definition - CRYPTOGRAPHIC ACCELERATOR explanation. Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license. In computing, a cryptographic accelerator is a co-processor designed specifically to perform computationally intensive cryptographic operations, doing so far more efficiently than the general-purpose CPU. Because many servers' system load consists mostly of cryptographic operations, this can greatly increase performance. Intel's AES-NI is by far the most common cryptographic accelerator in commodity hardware. VIA PadLock is another recent example. Several operating systems provide some support for cryptographic hardware. The BSD family of systems has the OpenBSD Cryptographic Framework (OCF), Linux systems have the Crypto API, Solaris OS has the Solaris Cryptographic Framework (SCF) and Microsoft Windows has the Microsoft CryptoAPI. Some cryptographic accelerators offer new machine instructions and can therefore be used directly by programs. Libraries such as OpenSSL and LibreSSL support some such cryptographic accelerators. Almost all Unix-like operating systems use OpenSSL or the fork LibreSSL as their cryptography library. These libraries use cryptographic accelerators such as AES-NI if available.

Marlon Dutra https://2016.pycon-au.org/schedule/68/view_talk Today, more than ever before, security is part of the fabric of the internet, with most websites defaulting to https over the historically used default of unsecured http. Whenever you see a URL starting with https:// (https:), your browser is sending the HTTP (or Spdy) traffic through a Transport Layer Security (TLS) tunnel. Part of establishing this secure tunnel involves your browser validating an X.509 certificate provided by the website you're viewing. This allows you to be sure that the server on the other end is who it says it is before you send some potentially sensitive information like your username and password. This is just one example of how these technologies can be used, but there are many more. In distributed systems that communicate sensitive information, like user data, it is imperative to have a mutual authentication mechanism, where the client is confident it is talking to the right service, as well as the service being confident it is talking to the right client. Beyond strong authentication, it is usually desirable to have some authorization logic, to prevent clients from having unrestricted access to all services. Since any TCP communication can be tunneled through TLS, and TLS supports such mutual authentication through X.509 certificates, they are the perfect set of tools for the job. The problem to solve then becomes how you manage all of these certificates. Crafting simple certificates with the openssl command line is a bit tricky but doable. However, modern certificates support a variety of advanced features and it is quite complicated to take full advantage of them through the command line, especially in a programmatic way. This is where Python can be a powerful tool. Through the use of certain libraries, you can inject valuable information into your certificates that can be used for many purposes, such as establishing a robust authorization model for a service. In this session we'll explore some of the ways you can leverage X.509 certificate features to better protect your systems and data. We'll give specific examples of how to use Python for the programmatic management of complex certificates as well as talking about how the largest website on the Internet, Facebook, handles hundreds of thousands of such certificates in its internal infrastructure, using these same approaches. By the end of this talk, you will understand how to craft your own elaborate certificates with Python and how to use them to secure communications between networked services.

Using dedicated hardware is common to accelerate crypto- graphic operations: complex operations are managed by a dedicated co- processor, and data is transferred between RAM and the crypto-engine through DMA operations. The CPU is therefore free for other tasks, which is vital in embedded environments with limited CPU power. In this work we discuss and benchmark XTS-EAS, using either software or mixed approaches, using Linux and dm-crypt, and a low power AT- MEL board, featuring an AES crypto-engine that supports ECB-AES but not the XTS-AES mode. We show that the dm-crypt module used in Linux for full disk encryption has limitations that can be relaxed when considering higher block sizes. We demonstrate that performance gains almost by a factor two are possible, which opens new opportunities for future use-cases.

Heartbleed is a security bug in the open-source OpenSSL cryptography library, widely used to implement the Internet's Transport Layer Security (TLS) protocol. This vulnerability is due to a missing bounds check in the handling of the Transport Layer Security (TLS) heartbeat extension. A fixed version of OpenSSL was released on April 7, 2014, at the same time as Heartbleed was publicly disclosed. At that time, some 17 percent (around half a million) of the Internet's secure web servers certified by trusted authorities were believed to be vulnerable to the attack, allowing theft of the servers' private keys and users' session cookies and passwords. The Electronic Frontier Foundation, Ars Technica, and Bruce Schneier all deemed the Heartbleed bug "catastrophic". Forbes cybersecurity columnist Joseph Steinberg wrote, "Some might argue that [Heartbleed] is the worst vulnerability found (at least in terms of its potential impact) since commercial traffic began to flow on the Internet HOW TO DO?

Learn how to install free SSL on Wordpress having GoDaddy hosting Let's Encrypt is the first free and open CA We generate certificates using their ACME server by using domain validation. Private Keys are generated in your browser and never transmitted. For modern browsers we generate a private key in your browser using the Web Cryptography API and the private key is never transmitted. The private key also gets deleted off your browser after the certificate is generated. If your browser does not support the Web Cryptography API then the keys will be generated on the server using the latest version of OpenSSL and outputted over SSL and never stored. For the best security you are recommended to use a supported browser for client generation. You can also provide your own CSR when using manual verification in which case the private key is handled completely on your end. https://www.pixelbyme.com/install-godaddy-ssl-certificate-free/

Secure boot helps to plug security vulnerabilities for servers in the data center. The primary requirement to implement secure boot using UEFI is the support for secure storage on the server platform. Existing support for secure storage in implementations of UEFI such as EDK2 are x86 specific relying on the x86 SMM operating mode to provide a hardware enforced sandbox execution environment. AArch64 based platforms rely on S-EL0/1 to provide such a sandbox execution environment to implement secure storage but the upstream EDK2 support for secure storage requires design changes to extend it for AArch64 platforms. This proposal presents those design changes with detailed information of the proposed changes.

Lost and Found Certificates: dealing with residual certificates for pre-owned domains By Ian Foster, Hacker & Dylan Ayrey, Hacker Summary of Presentation: When purchasing a new domain name you would expect that you are the only one who can obtain a valid SSL certificate for it, however that is not always the case. When the domain had a prior owner(s), even several years prior, they may still possess a valid SSL certificate for it and there is very little you can do about it. Using Certificate Transparency, we examined millions of domains and certificates and found thousands of examples where the previous owner for a domain still possessed a valid SSL certificate for the domain long after it changed ownership. We will review the results from our ongoing large scale quantitative analysis over past and current domains and certificates. We'll explore the massive scale of the problem, what we can do about it, how you can protect yourself, and a proposed process change to make this less of a problem going forwards. We end by introducing BygoneSSL, a new tool and dashboard that shows an up to date view of affected domains and certificates using publicly available DNS data and Certificate Transparency logs. BygoneSSL will demonstrate how widespread the issue is, let domain owners determine if they could be affected, and can be used to track the number of affected domains over time. Speaker Background: Ian Foster Ian enjoys researching systems and networking problems and solutions in an effort to make the world more secure. He has published research papers analyzing the new gTLD land rush and crawling and parsing most WHOIS records. From demonstrating how insecure aftermarket OBD "dongles" can be used to compromise and take over automobiles; to measuring the paths an email traverses online with encryption in an effort to increase integrity, authenticity, and confidentiality; and more. During the day Ian is a Security Engineer fighting for the users. Dylan Ayrey Dylan is a security engineer, who in his free time authors lots of open source projects, such as truffleHog. He graduated college in 2015 and has been working in security ever since.
