linux.git/arch/powerpc/crypto, branch v6.16 Linux kernel source tree crypto: powerpc/sha256 - implement library instead of shash 2025-05-05T10:20:43+00:00 Eric Biggers ebiggers@google.com 2025-04-28T17:00:31+00:00 1a49c573bf886349c7bc958b331c700cf18601d8 Instead of providing crypto_shash algorithms for the arch-optimized SHA-256 code, instead implement the SHA-256 library. This is much simpler, it makes the SHA-256 library functions be arch-optimized, and it fixes the longstanding issue where the arch-optimized SHA-256 was disabled by default. SHA-256 still remains available through crypto_shash, but individual architectures no longer need to handle it.
