From 243201772cc6d583fae9eba81cb2c2c7425bc564 Mon Sep 17 00:00:00 2001
From: Clemens Lang <cllang@redhat.com>
Date: Mon, 21 Feb 2022 17:24:44 +0100
Subject: Selectively disallow SHA1 signatures
For RHEL 9.0, we want to phase out SHA1. One of the steps to do that is
disabling SHA1 signatures. Introduce a new configuration option in the
alg_section named 'rh-allow-sha1-signatures'. This option defaults to
false. If set to false (or unset), any signature creation or
verification operations that involve SHA1 as digest will fail.
This also affects TLS, where the signature_algorithms extension of any
ClientHello message sent by OpenSSL will no longer include signatures
with the SHA1 digest if rh-allow-sha1-signatures is false. For servers
that request a client certificate, the same also applies for
CertificateRequest messages sent by them.
For signatures created using the EVP_PKEY API, this is a best-effort
check that will deny signatures in cases where the digest algorithm is
known. This means, for example, that that following steps will still
work:
$> openssl dgst -sha1 -binary -out sha1 infile
$> openssl pkeyutl -inkey key.pem -sign -in sha1 -out sha1sig
$> openssl pkeyutl -inkey key.pem -verify -sigfile sha1sig -in sha1
whereas these will not:
$> openssl dgst -sha1 -binary -out sha1 infile
$> openssl pkeyutl -inkey kem.pem -sign -in sha1 -out sha1sig -pkeyopt digest:sha1
$> openssl pkeyutl -inkey kem.pem -verify -sigfile sha1sig -in sha1 -pkeyopt digest:sha1
This happens because in the first case, OpenSSL's signature
implementation does not know that it is signing a SHA1 hash (it could be
signing arbitrary data).
