Linux Cryptography

The Linux kernel incorporates a robust and versatile cryptographic subsystem. This subsystem provides a comprehensive suite of cryptographic primitives and algorithms, acting as a foundational security layer for the entire system. By implementing these functions directly within the kernel, Linux ensures that crucial cryptographic operations, such as data encryption, secure hashing, etc., are performed with hardware acceleration (if available) and are readily available to various kernel components and user-space applications. This is vital for securing everything from network communications and filesystems to system integrity.
