From f1799d17285ca99243328cd92133a9f84ee3a593 Mon Sep 17 00:00:00 2001 From: Eric Biggers Date: Sat, 25 Oct 2025 22:50:31 -0700 Subject: crypto: sha3 - Reimplement using library API Replace sha3_generic.c with a new file sha3.c which implements the SHA-3 crypto_shash algorithms on top of the SHA-3 library API. Change the driver name suffix from "-generic" to "-lib" to reflect that these algorithms now just use the (possibly arch-optimized) library. This closely mirrors crypto/{md5,sha1,sha256,sha512,blake2b}.c. Implement export_core and import_core, since crypto/hmac.c expects these to be present. (Note that there is no security purpose in wrapping SHA-3 with HMAC. HMAC was designed for older algorithms that don't resist length extension attacks. But since someone could be using "hmac(sha3-*)" via crypto_shash anyway, keep supporting it for now.)
