From 43767ff9954af58e4973d6e1b2941d260eaa2794 Mon Sep 17 00:00:00 2001 From: Alan Coopersmith Date: Tue, 3 Mar 2026 13:12:12 -0800 Subject: [PATCH] os: fix sha1 build error with Nettle 4.0 Nettle 2.6 (released in 2013) split the sha.h header into sha1.h & sha2.h, but left the sha.h header for compatibility until the recent Nettle 4.0 release finally removed it. Nettle 4.0 also dropped the length argument from the sha1_digest function.
