To handle cryptography, the Linux kernel has its own API enabling common methods of encryption, decryption and your favourite hash functions! Learn about the use of hash functions and symmetric key encryption in the Linux kernel in the Linux Kernel Module Programming Guide.
OpenSSL has patched two high-severity crypto bugs. Upgrade now!
SSH keys play a critical role in server and network security, yet are too often overlooked by admins, IT professionals and security teams.
"Modern challenges require modern security approaches." Enterprises must transition to using passwordless solutions in order to protect against emerging threats – which is where SSH key-based authentication comes in handy. Learn about the SSH protocol in this comprehensive article.
Are you using full-disk encryption to protect your data? If so, you may want to reconsider after reading this article.
Here's a link to an OpenBSD page that describes what crypto features are capable with it. Specifically, as pointed out on slashdot, http://www.openbsd.org/crypto.html#hardware is a link to new support for hardware crypto devices using OpenBSD. We'd be happy to post this kind of information in the future -- just send it along.
Cartesi has announced the launch of their Descartes SDK Documentation portal, which represents a leap forward for the Cartesi team in fulfilling their ambition in bridging the world of Linux open-sourced software with the inherent security benefits of blockchain technology.
HTTP/3 brings improved performance and reliability, as well as various security and privacy benefits - but there are some serious concerns that need to be considered.
IBM's new toolkit, which will soon be available for Linux, aims to give developers easier access to fully homomorphic encryption, a technology that protects sensitive data by allowing for computation and analysis of data while keeping it encrypted.
Could Wireguard be the open-source answer to VPN shortfalls? Find out in this article.
WireGuard has finally made it into the mainline Linux kernel - meaning Dynamic Kernel Module Support (DKMS) builds will no longer be necessary, making routine kernel upgrades significantly faster!
COVID-19 is forcing browser makers including Google and Mozilla to continue supporting the TLS 1.0 and TLS 1.1 protocols.
Have you heard about IPFire's new method of cryptographic kernel rootkit protection? IPFire is an open-source software that protects the network from external attacks and prevents intrusion.
The most popular free certificate signing authority Let's Encrypt is going to revoke more than 3 million TLS certificates within the next 24 hours that may have been issued wrongfully due to a bug in its Certificate Authority software.
We issued our billionth certificate on February 27, 2020. We’re going to use this big round number as an opportunity to reflect on what has changed for us, and for the Internet, leading up to this event. In particular, we want to talk about what has happened since the last time we talked about a big round number of certificates -one hundred million.
Huawei can covertly access mobile networks through back doors meant for law enforcement, the U.S. has told allies in a bid to show that the firm poses a security threat.
Strong, unbroken encryption is essential in protecting users' privacy and the integrity of sensitive data, yet encryption technology is currently under threat in many countries.
Is a Linux SSH GUI in your future? Jack Wallen believes once you try Snowflake, there's no going back. If you are currently using Snowflake, we'd love to hear your thoughts!
The WireGuard VPN protocol, which is smaller, faster and easier to configure than IPsec, has been merged into Linus Torvalds' git repository for version 5.6 of the Linux kernel, the next release.
An election security group has said the Justice Department’s renewed calls for access to encrypted data could impact more than privacy, stating: “Any effort to diminish the effectiveness of encryption will inherently diminish the security and, potentially, the integrity, of our elections. Hostile actors will likely direct similar efforts at campaign officials, political organizations, and politically engaged individuals in future elections." What are your thoughts?
