From c0c5a1b786c3ddeb1d6076833b0cd54419e9e8ac Mon Sep 17 00:00:00 2001 From: naddy Date: Thu, 14 Dec 2017 21:07:39 +0000 Subject: [PATCH] Replace ED25519's private SHA-512 implementation with a call to the regular digest code. This speeds up compilation considerably. ok markus@ --- usr.bin/ssh/blocks.c | 246 ------------------------- usr.bin/ssh/crypto_api.h | 8 +- usr.bin/ssh/hash.c | 79 ++------ usr.bin/ssh/ssh-add/Makefile | 4 +- usr.bin/ssh/ssh-agent/Makefile | 4 +- usr.bin/ssh/ssh-keygen/Makefile | 4 +- usr.bin/ssh/ssh-keyscan/Makefile | 4 +- usr.bin/ssh/ssh-keysign/Makefile | 4 +- usr.bin/ssh/ssh-pkcs11-helper/Makefile | 4 +- usr.bin/ssh/ssh/Makefile | 4 +- usr.bin/ssh/sshd/Makefile | 4 +- 11 files changed, 30 insertions(+), 335 deletions(-) delete mode 100644 usr.bin/ssh/blocks.c diff --git a/usr.bin/ssh/blocks.c b/usr.bin/ssh/blocks.c deleted file mode 100644 index ba569b00a88..00000000000 --- a/usr.bin/ssh/blocks.c +++ /dev/null @@ -1,246 +0,0 @@ -/* $OpenBSD: blocks.c,v 1.3 2013/12/09 11:03:45 markus Exp $ */ - -/* - * Public Domain, Author: Daniel J.
