libkcapi
A user-space library providing high-performance access to the Linux kernel crypto API via Netlink.
What is libkcapi?
libkcapi is a user-space interface library that provides access to the Linux kernel's cryptographic API via Netlink. It allows applications to perform cryptographic operations (e.g., encryption, hashing, random number generation) directly through the kernel, eliminating the need for user-space crypto implementations. The library focuses on high performance by avoiding memory copies and offering a simple API.
Linux developers and system programmers who need efficient, kernel-backed cryptographic operations in user-space applications, particularly those building security tools, utilities, or embedded systems.
Developers choose libkcapi for its zero-copy design, which maximizes performance, and its direct integration with the Linux kernel crypto API, ensuring reliability and consistency. It also provides drop-in replacements for common tools like OpenSSL and coreutils, simplifying deployment.
