Rustls began with a first commit on May 2, 2016. Progress was quick: a month later, on June 5, it could interoperate with most sites on the web. The first release, 0.1.0, followed on August 27, 2016 - less than four months after the first commit. [...] From the 0.1.0 release, the project moved through a long series of releases over the following eight years, building out functionality, hardening and refining the API. That sequence of release lines culminated in 0.23, released on February 29, 2024. The 0.23 release line has been a stable one: in the time since, it has seen 43 non-breaking releases. That stability didn't come with stagnation. The 0.23 line delivered a wide range of important features, including a FIPS-certified cryptography option, certificate compression, Encrypted ClientHello, post-quantum cryptography, and performance improvements. ## Automatic Key Exchange: faster, post-quantum secure origin handshakes for 45 billion daily connections (and counting) DevFeed: [Automatic Key Exchange: faster, post-quantum secure origin handshakes for 45 billion daily connections (and counting)]() Original publisher: [Read original article]() Author: Alex Krivit Published: 2026-09-08T13:10:00Z Content type: release Language: en Sources: [Cloudflare Blog]() Topics: [Cryptography](), [SSL](), [Latency](), [Encryption]() Tags: [application-security](), [application-services](), [cloudflare](), [encryption](), [latency](), [performance](), [post-quantum](), [research](), [ssl](), [tls]() ### AI overview Cloudflare announces Automatic Key Exchange, which probes TLS 1.3 origins for supported key-agreement algorithms and uses the preferred option on the first connection attempt.

It highlights harvest-now, decrypt-later attacks, the vulnerability of RSA, ECC, and Diffie-Hellman to Shor's Algorithm, and the expected resilience of AES-256. ### Source excerpt When quantum computers become generally available, they'll be able to crack current public-key cryptographic algorithms, putting digitally stored and transmitted data at risk. But the threat already exists, as attackers use the "harvest now, decrypt later" tactic. Discover why building a comprehensive cryptographic inventory and executing a phased operational strategy are critical for protecting your data against quantum computing attacks. Key takeaways Quantum computing risks are an operational threat today due to "harvest now, decrypt later" (HNDL) tactics, in which adversaries actively harvest and store encrypted data to decrypt it retroactively once quantum capabilities mature. When run on a quantum computer that's powerful enough, Shor's Algorithm will break foundational asymmetric infrastructure like the RSA, ECC, and Diffie-Hellman algorithms, although symmetric encryption standards like AES-256 are expected to remain secure against quantum attacks. Globally, more regulatory bodies are starting to mandate a comprehensive cryptographic inventory, making absolute visibility across the digital environment a prerequisite for an orderly post-quantum migration. Transitioning to quantum-resistant cryptography requires a phased operational strategy spanning discovery, prioritization, remediation, and verification. The quantum threat to modern security architecture Future quantum computers will represent a threat to the foundational security architecture that protects digital data. For decades, the global economy, national security apparatus, and critical infrastructure have relied on asymmetric cryptography, specifically RSA and elliptic curve cryptography (ECC), to secure data in transit, authenticate identities, and protect digital signatures. The mathematical difficulty of factoring large integers or solving discrete logarithm problems has long provided a robust shield against cyber attacks launched using conventional computing capabilities. However, the rapid mat ## Go 1.27 is released DevFeed: [Go 1.27 is released]() Original publisher: [Read original article]() Author: Nicholas Husin, on behalf of the Go team Published: 2026-08-19T00:00:00Z Content type: release Language: en Sources: [The Go Blog]() Topics: [releases]() Tags: [go](), [json](), [memory](), [performance](), [post-quantum](), [release](), [release-notes](), [toolchain]() ### AI overview Go 1.27 releases language, toolchain, runtime, and standard-library updates, including generic methods, JSON processing additions, allocation improvements, and new UUID support. ### Source excerpt Go 1.27 adds generic methods, encoding/json/v2 package, uuid package, faster memory allocation, goroutine leak profiles, and more. ## Some thoughts about Anthropic's new cryptanalysis results DevFeed: [Some thoughts about Anthropic's new cryptanalysis results]() Original publisher: [Read original article]() Author: Matthew Green Published: 2026-07-29T14:23:30Z Content type: opinion Language: en Sources: [Matthew Green]() Topics: [Cryptography](), [Claude](), [anthropic](), [Post-Quantum](), [Algorithm]() Tags: [academics](), [ai](), [algorithm](), [anthropic](), [artificial-intelligence](), [attacks](), [chatgpt](), [claude](), [llm](), [post-quantum](), [research](), [security](), [technology](), [thoughts]() ### AI overview The article offers commentary on two cryptanalysis results published by Anthropic and produced by Claude Mythos: an attack on the proposed HAWK post-quantum signature scheme and an improved attack on reduced-round AES.

It explains that adopting these primitives involves size, performance, and integration tradeoffs. ### Source excerpt Post-quantum cryptography is now one pip-install away for the entire Python ecosystem. With funding from the Sovereign Tech Agency, we implemented support for ML-KEM, the NIST-standard key-establishment primitive, and ML-DSA, the NIST-standard digital-signature primitive, in pyca/cryptography. On June 22, 2026, the White House ordered the U.S. government to accelerate its transition to post-quantum cryptography. The order says large-scale quantum computers, especially in adversarial hands, will threaten widely used cryptographic systems, and that attackers may already be collecting encrypted data now so they can decrypt it later. It also sets concrete migration deadlines: high-value and high-impact federal systems must use post-quantum key establishment by December 31, 2030, and post-quantum digital signatures by December 31, 2031. And even if you don't care about quantum resistance, that's not a problem because quantum resistance isn't the main benefit of post-quantum crypto. That transition cannot happen only at the policy layer. Every application that signs packages, validates certificates, establishes secure channels, or protects long-lived secrets depends on cryptographic libraries. If those libraries do not expose post-quantum algorithms, the software stack cannot migrate. Almost every Python program that touches cryptography goes through pyca/cryptography. It's currently the eleventh most-downloaded package on PyPI, pulling 1.2 billion downloads in the last month alone. The pyca/cryptography package handles the cryptographic operations of projects like Ansible, Certbot (the Let's Encrypt client), Apache Airflow, paramiko (the Python-only SSH client), and many others. If pyca/cryptography doesn't ship post-quantum primitives, the Python ecosystem can't begin to migrate. Post-quantum support is now one pip install away As of cryptography>=48, support for post quantum algorithms is just a pip install away.

It explains why Grover's algorithm does not reduce the practical security of AES-128 and SHA-256 enough to justify replacing 128-bit symmetric keys, while asymmetric cryptography remains affected by Shor's algorithm. ### Source excerpt There is no need to update symmetric key sizes as part of the post-quantum transition, due to the details of how Grover's algorithm scales. Most authorities agree. ## A Cryptography Engineer's Perspective on Quantum Computing Timelines DevFeed: [A Cryptography Engineer's Perspective on Quantum Computing Timelines]() Original publisher: [Read original article]() Author: Filippo Valsorda Published: 2026-04-06T15:00:00Z Content type: opinion Language: en Sources: [Filippo Valsorda]() Topics: [Quantum Computing](), [Cryptography](), [Post-Quantum](), [Security, Privacy and Abuse Prevention]() Tags: [attacks](), [cryptography](), [hardware](), [post-quantum](), [quantum](), [quantum-computing](), [research]() ### AI overview A cryptography engineer explains why recent research on quantum algorithms, hardware, qubits, and error correction has changed his assessment of the urgency of migrating to quantum-resistant cryptography.
