TIL: Ever wanted to compress data or use cryptographic algorithms but you don't want to link to C libraries or you're just plain lazy?
The Linux kernel has you covered! Create a socket of type AF_ALG, bind to your favorite algorithm, send() in your data and recv() it back!
This seems to support deflate, SHA, RSA and some more on ppc64le and additionally even zstd, chacha, lzo, hmac and more on ARM!
