The Linux Crypto API for user applications

What this post added

This post introduces the Linux Kernel Crypto API as a mechanism for user applications to leverage hardware-accelerated cryptographic operations. It details how applications can interact with the kernel's crypto modules, explores the performance implications of using the API compared to user-space libraries like OpenSSL, and highlights the benefits of offloading encryption/decryption to the kernel for enhanced security and performance, particularly when integrated with kernel key retention services.
