From add890c9f9d2d1d79184ded72f23b37b164fc673 Mon Sep 17 00:00:00 2001 From: Eric Biggers Date: Mon, 22 Jul 2019 09:26:23 -0700 Subject: fs-verity: add SHA-512 support Add SHA-512 support to fs-verity. This is primarily a demonstration of the trivial changes needed to support a new hash algorithm in fs-verity; most users will still use SHA-256, due to the smaller space required to store the hashes. But some users may prefer SHA-512.
