At the 2026 Linux Security Summit, Eric Biggers unveiled new library APIs for the kernel's cryptography framework, simplifying cryptographic function usage and addressing flaws in the traditional API.
Eric Biggers took the stage at the 2026 Linux Security Summit North America to unveil promising developments in the Linux kernel's cryptography framework. Highlighting the shortcomings of the traditional crypto API, Biggers introduced new library APIs designed to streamline cryptographic function usage for developers and kernel maintainers.
The traditional crypto API has long been a source of frustration, its complexity and fragility often leading to inefficiencies and errors. Biggers demonstrated how the new library APIs provide a more intuitive interface, allowing developers to integrate cryptographic functions without the headaches of the past. By abstracting intricate details, the new APIs make life easier for those involved in kernel development.
In his presentation, Biggers walked through specific examples that showcased the frailty of the original API. These real-world scenarios underscored the need for modernization. The introduction of library APIs not only simplifies development but also enhances security by reducing the likelihood of implementation errors.
Developers and sysadmins alike have been eager for such improvements. The new APIs represent a significant step forward in making the kernel's cryptographic capabilities more accessible and less error-prone. As these changes roll out, the community will undoubtedly benefit from a more robust and developer-friendly cryptographic framework.
The Linux Camp teaches these topics as hands-on labs on real virtual machines, verified as you type.
