WSL recently went open source but even before then it was really good.

Windows Subsystem for Linux is a thing by microsoft which just allows you to run linux inside of your windows PC. I just used it whenever i needed some command line tooling or shit that windows doesn't have (grep, wc, openssl) but i found out only a billion years later it can run full gui apps (just download them and run them from the command line) or you can also run an Entire Desktop environment to basically just have a Linux system inside of your windows installation without any virtual machines or messing about with dual booting or partitioning.

WSL will run a lot worse than normal linux however its (i think) much easier to set up and you can access all your normal windows files from it as well.

It would be good to try if you want to switch to linux but you wanna try it out, however i dont think i have any windows devices anymore to see how well it works and how easy it is to set up a DE

Microsoft PQC ML-KEM, ML-DSA algorithms for windows & Linux

Microsoft has made significant progress in post-quantum cryptography (PQC) with SymCrypt-OpenSSL version 1.9.0 for Linux and Windows Insiders (Canary Channel Build 27852 and higher). This modification allows customers to test PQC algorithms like ML-KEM and ML-DSA in actual operational situations. Linux and Windows Insiders Get Quantum-Resistant Cryptography.

Due to quantum computing, modern cryptography faces significant challenges. Microsoft is providing early access to PQC capabilities to help organisations evaluate the performance, interoperability, and integration of these novel algorithms with current security infrastructure. This pragmatic approach helps security teams identify challenges, refine implementation strategies, and ease the transition when industry standards evolve. Early adoption also helps prevent new vulnerabilities and protect private data from quantum threats.

Next-generation cryptography API update

Cryptography API: Next Generation (CNG) enhancements are crucial to this Windows edition. CryptoAPI will be superseded forever by CNG. It is extendable and cryptography-independent. Programmers designing programs that allow safe data production and sharing, especially across insecure channels like the Internet, use CNG. CNG developers should know C, C++, and Windows, though it's not required. Cryptography and security knowledge are also advised.

Developers designing CNG cryptographic algorithm or key storage providers must download Microsoft's Cryptographic Provider Development Kit. First to support CNG are Windows Server 2008 and Vista. The latest PQC upgrades use encrypted communications, CNG libraries, and certificates.

New Windows PQC Algorithms

Microsoft is providing ML-KEM and ML-DSA, two NIST-standardized algorithms, to Windows Insiders via CNG updates.

Developers can now try ML-KEM for public key encapsulation and key exchange. This helps prepare for the “harvest now, decrypt later” scenario, in which hackers store encrypted data now to use a quantum computer to decipher it tomorrow. Microsoft proposes a hybrid method that combines ML-KEM with RSA or ECDH for defence in depth throughout the transition, ideally with NIST security level 3 or higher.

By incorporating ML-DSA in CNG, developers can evaluate PQC algorithms for digital signature verification of identity, integrity, or authenticity. Microsoft recommends a hybrid approach, using ML-DSA alongside RSA or ECDSA throughout the transition.

Size and performance will affect these new algorithms, according to preliminary research. Customers should analyse these consequences on their environment and apps early.

Customers can test installing, importing, and exporting ML-DSA certificates to and from the certificate store and CNG and PQC updates using the Windows certificate API interface win crypt. PQ certificate chains and trust status can be verified.

PQC Linux Features

Microsoft is releasing PQC upgrades in the SymCrypt provider for OpenSSL 3 because Linux customers expect them. The provider allows Linux programmers to use OpenSSL's API surface, which uses SymCrypt cryptographic procedures.

The latest IETF internet draft recommends SymCrypt-OpenSSL 1.9.0 for TLS hybrid key exchange testing. This lets you prepare for “harvest now, decrypt later” risks early. This feature allows for a full study of how hybrid PQC algorithms affect handshake message length, TLS handshake delay, and connection efficiency. Such research are needed to understand PQC's actual trade-offs.

It is important to remember that SymCrypt-OpenSSL will be updated when standards change to ensure compliance and compatibility, and that Linux updates are based on draft specifications.

What Next?

PQC's Linux and Windows Insider integration must be described first.

Plans call for more features and improvements:

Upcoming efforts include adding SLH-DSA to SymCrypt, CNG, and SymCrypt-OpenSSL.

Add new algorithms to assure broad compatibility as PQC standards expand, improve security, and comply with international law.

Working with industry partners on X.509 standardisations for the IETF's LAMPS working group's broad use of ML-DSA algorithm, composite ML-DSA, SLH-DSA, ML-KEM, and LMS/XMSS. These efforts will involve PKI use cases and signature approaches for firmware and software signing.

TLS hybrid key exchange for Windows users is being implemented using the Windows TLS stack (Schannel).

Develop and standardise quantum-safe authentication methods for TLS and other IETF protocols including SLH-DSA, Composite ML-DSA, and pure ML-DSA with the IETF. SymCrypt for OpenSSL, Windows TLS stack (Schannel), and Linux Rust Wrapper will deliver standards as they are established.

Active Directory Certificate Services actively supports PQC. Customers setting up a Certification Authority (CA) can use ML-DSA-based CA certificates. PQC algorithms sign CA-issued CRLs for customers who enrol in end-entity certificates. We'll support all ADCS role services.

Supporting PQC certificates in Microsoft Intune's Certificate Connector lets endpoints and mobile devices sign up for quantum-safe credentials. This will unlock SCEP & PKCS #12 scenarios for on-premises CAs utilising ADCS.

TLS 1.3 is essential for PQC. Microsoft strongly advises customers to abandon older TLS protocols.

These new features will be available to Windows Insiders and development channels for real-world testing. Microsoft can make incremental modifications before release by getting feedback on usability, security, and compatibility. Microsoft will distribute dependable and compatible solutions to supported platforms using a flexible and adaptable approach after standards are finalised. Working with standards organisations and industry partners will ensure features fit global regulatory framework and ecosystem needs.

Future challenges and prospects

Due to their youth, PQC algorithms are an emerging field. This shows how important “Crypto Agility” is in building solutions that can use different algorithms or be modified when standards change.

Microsoft recommends hybrid PQ and crypto-agile solutions for PQC deployment. Composite certificates and TLS hybrid key exchange use PQ and RSA or ECDHE algorithms. Pure PQ implementations should increase as algorithms and standards improve.

Despite integration being a turning point, PQC algorithms' performance, interoperability with current systems, and acceptance remain issues.

Performance: PQC algorithms often require more processing power than standard algorithms. Its efficient implementation without affecting system performance is a big hurdle. Technology for hardware acceleration and optimisation is essential. Keccak is utilised in many PQ algorithms, and hardware acceleration is needed to boost its performance for PQC cryptography.

Larger key encapsulation and digital signatures, especially in hybrid mode, may increase TLS round-trip time. Although signatures cannot be compressed, IETF proposals are examining certificate compression and TLS key sharing prediction. These effects should be assessed on applications and surroundings.

Adoption and Compatibility: PQC requires upgrading and replacing cryptographic infrastructure. Developers, hardware manufacturers, and service providers must collaborate to ensure legacy system compatibility and broad acceptance. Education and awareness campaigns and government-mandated compliance deadlines will boost adoption.

In conclusion

PQC incorporation into Linux and Windows Insiders is a major quantum future preparation step. Microsoft is proactively fixing cryptographic security flaws to help create a digital future that uses quantum computing and reduces security risks. PQC is needed to protect data, communications, and digital infrastructure as quantum computing evolves. Cooperation and security are needed to build stronger systems.

even if you don't care about companies (which is valid), you absolutely should care about the issue of commercial/research abandonware. like, this isn't just an issue in research labs, whether commercial or academic. this is an issue at the heart of everything we touch. this is what right to repair is about, too, and why the dmca is so terrible, because you know what a car is now? it's a fucking computer with a motor in it. and what happens when they no longer want to support the software in that computer? what happens when there's a bug that's too expensive to fix?

like, IT security is deeply unsexy, but in a world where every piece of your life could potentially be ruined by a combination of corporate apathy towards infosec and reliance on both abandonware and open-source project maintainers, this is a real issue.

and you know what? it's all fucking capitalism at the bottom. the maintainers of openssl, the suite that keeps most of your internet traffic safe, could make sure that the suite was audited regularly, and that they could patch it promptly when vulnerabilities were discovered, if they didn't have to worry about paying their bills. the microscope software up-thread wouldn't be abandonware running on windows 95 if profit weren't the primary motive. decades of vital research data wouldn't be locked to a proprietary and unsupported format if profit weren't a primary motive. software could be supported indefinitely if "profit margins" weren't a thing. it's all fucking capitalism.

abandonware should be public domain. force companies to actively support and provide products if they don't wanna lose the rights to them

TPM: A Guide to Understanding Your Computer’s Security Chip

What is Trusted Platform Module (TPM) A Trusted Platform Module (TPM) is a secure cryptoprocessor chip on your computer’s motherboard.

First Contact TPM for Windows The BitLocker drive encryption, the Virtual Smart Card features, and the Crypto Provider are among the security components of the Microsoft Windows operating system that depend on TPM-based capabilities. In fact, Trusted Platform Module 2.0 needs to be activated in ALL desktop and server variants of Windows 10 and 11. By using remote attestation in conjunction with the system’s Trusted Platform Module to allow Measured Boot, the configuration of the system is protected from undetectable threats like rootkits.

On Intel’s Windows machine, Intel can quickly verify some Trusted Platform Module details by navigating to the Security Devices area of the Device Manager screen.

TPM details by navigating to the Security Devices area of the Device Manager screen.

Now let’s engage with it. Now that a terminal window is open, let’s extract some basic system data. There are numerous powershell cmdlets available in Windows that can be used right away.

Get-Tpm retrieves the following data from the module:

Intel can also use this information to deduce some details about the underlying system: For instance, if the platform is equipped with and employing Platform Trust Technologies (PTT), “Intel” will appear in the manufacturer section here. Here, a Trusted Platform Module from the company STM is being used.

Intel must communicate with Windows Core Security features, namely the Trusted Platform Module Base Services software component and related API, in order to utilise the Trusted Platform Module from an application standpoint. Microsoft offers tools and wrappers to facilitate the integration of these processes more quickly.

Then intel will begin examining these after that.

Linux-based TPM First Contact Working with keys securely across any TPM 2.0 compatible module is made feasible by a set of standardised commands and libraries that enable the use of TPMs for key loading and storage in Linux.

At a high level, you can check if a TPM is present in the system by running the following command in the system log: dmesg | grep -i tpm.

Here is a step-by-step guide to several fundamental Linux system interactions: Required conditions: Install a TPM 2.0 chip on the target machine. Install TPM 2.0 software. These packages differ per Linux distribution.The tpm2-tools and tpm2-tss packages are popular. Initialise TPM: Initialise the TPM before using it. Initialise the TPM with tpm2 startup. Establish an Application Key: Create a key that is unique to your application and that you wish to keep in the TPM.You can use a software library like OpenSSL or a Trusted Platform Module library like tpm2-tools to generate this key.

The following is one method of generating an RSA keypair: RSA algorithm -out appkey.pem -openssl genpkey

Fill the TPM with the Key: To load your application-specific key into the TPM, use the TPM 2.0 tools. For this, you’ll usually use the tpm2 load command: tpm2 load -C appkey.pub -r appkey.priv -u context.out This command saves the context of the key in the context.out file and loads it into the TPM. This context is necessary for using the key later on. Apply the resident key (TPM): You can use this commands or libraries such as tpm2-tss to execute cryptographic operations on the TPM-resident key when your programme needs to access it. To sign data using the TPM key, for instance, run the following commands: tpm2 sign -c context.out -g sha256 -m data.txt -s signature.bin Using the TPM-resident key, this command signs the data and stores the signature in signature.bin. Unload the Key (Optional): You can use the tpm2 flushcontext command to unload the TPM-resident key if you no longer require it: tpm2 flushcontext -c context.out. This releases the key’s associated TPM resources. Shutdown and Cleanup (Optional): You can use the tpm2 shutdown command to terminate the Trusted Platform Module once your programme has finished utilising it. Analysing TPM 2.0 thoroughly Advancements in Computer Security Trusted Platform Module (TPM) 2.0 hardware boosts computer security. It protects your system and encryption keys as a secure cryptoprocessor. Essential Features: Cryptographic Key Management: TPM 2.0 securely produces, stores, and utilises keys.Data encryption, digital signatures, and secure communication require these keys. TPM 2.0’s hardware isolation makes key theft and tampering much harder than with software-based systems.

Platform Integrity Validation: Trusted Platform Module 2.0 monitors firmware and other critical software. It looks for any unauthorised changes that might point to malware or efforts at tampering. TPM 2.0 can protect your data by stopping the system from booting if something suspect is found.

Platform Attestation: The firmware and software of your system can be reported on using Trusted Platform Module 2.0. Other security measures or reliable organisations can use these reports, known as attestations, to confirm the integrity of the system. This is useful for secure boot environments and for assessing a system’s health prior to allowing access to resources that are sensitive.

Benefits of TPM 2.0: BitLocker Drive TPM 2.0 securely holds encryption keys, strengthening encryption and other functions. This makes data access tougher for unauthorised parties, even if they reach your device.

Enhanced Platform Security: Your system will boot with authentic, unaltered firmware and software thanks to the platform integrity checks. This lessens the chance that malware will compromise your system remotely.

More Robust User Authentication: Trusted Platform Module 2.0 can be paired with Windows Hello and other comparable technologies to provide more reliable two-factor authentication. By requiring a physical factor in addition to a password, like a fingerprint or facial recognition, this strengthens security. TPM 2.0, Win11:

Microsoft says Windows 11 needs Trusted Platform Module 2.0. This shows how crucial hardware-based security capabilities are becoming in the battle against more complex assaults. The good news is that TPM 2.0 functionality is probably pre-installed on the majority of PCs made in the last few years. It may, however, be inactive by default in the BIOS settings.

Beyond the Fundamentals: Flexibility: TPM 2.0 takes a “library” approach, in contrast to its predecessor. This implies that Trusted Platform Module 2.0 features can be selected by manufacturers based on what best meets their device and security requirements. Wider acceptance across multiple platforms from laptops to embedded systems is made possible by this versatility.

Future-Proofing: Expansion is a key design principle of TPM 2.0. As security risks evolve, it supports the installation of new functions and algorithms. This guarantees that Trusted Platform Module 2.0 will continue to be applicable and useful when new security threats arise.
