🔹 Kubernetes - Post-Quantum Cryptography in Kubernetes

This blog post discusses the significance of Post-Quantum Cryptography (PQC) in the context of Kubernetes, emphasizing the urgency to transition from classical cryptographic algorithms to PQC due to the potential threat posed by quantum computing. The article explains the role of PQC in securing TLS communications, focusing on key exchange and digital signatures, and highlights the current state of PQC adoption in the Kubernetes ecosystem. With the release of Kubernetes v1.33 in April 2025, which uses Go 1.24, the system now supports hybrid post-quantum key exchange by default, specifically the X25519MLKEM768 scheme. However, there are challenges such as Go version mismatches, which can lead to downgrades in cryptographic security, and issues related to the size of PQC public keys, which can affect packet transmission. While PQC key exchange mechanisms are progressing well, the adoption of PQC digital signatures is still developing, with larger keys and slower performance being notable obstacles. The post concludes by underscoring the importance of awareness and understanding of these emerging technologies to ensure the security and longevity of Kubernetes. 👉 Read more

🔹 Docker - GoFiber v3 + Testcontainers: Production-like Local Dev with Air

The blog post discusses the challenges of local development when applications depend on external services such as databases or message queues. These dependencies can result in fragile scripts and inconsistent environments. To address this, Fiber v3 and Testcontainers integrate real service dependencies into the application’s lifecycle, making them fully managed, reproducible, and developer-friendly. The upcoming release of Fiber v3 introduces new capabilities to enhance local development, ensuring that developers have a consistent and reliable environment that mimics production conditions. 👉 Read more

🔹 Java - Java Security Evolution - Out with the Old, In with the New

The blog post discusses the ongoing evolution of security within the Java Platform, emphasizing the need to adapt to emerging threats and weakened cryptographic protocols over time. It highlights key changes in Java security, including the permanent disabling of the Security Manager in JDK 24 and the introduction of support for quantum-resistant algorithms to bolster application security. The post also mentions plans for future enhancements, underscoring Java’s commitment to maintaining robust security standards. 👉 Read more

🔹 Golang - The FIPS 140-3 Go Cryptographic Module

The blog post discusses the introduction of a built-in, native FIPS 140-3 compliant mode in the Go programming language. This enhancement means that Go now supports cryptographic operations that meet the Federal Information Processing Standard (FIPS) 140-3, which is important for ensuring secure and standardized cryptographic practices. The new feature aims to provide developers with a reliable and compliant way to implement cryptography in their Go applications, enhancing security and meeting regulatory requirements. 👉 Read more

🔹 Helm - Helm @ KubeCon + CloudNativeCon EU ‘25
