From eb7eb1378cd15c4652884b3701d4c0ef27b5b8a6 Mon Sep 17 00:00:00 2001 From: David Woodhouse Date: Tue, 16 Oct 2018 07:41:17 -0700 Subject: [PATCH] Stop marking default digest for EC keys as mandatory ASN1_PKEY_CTRL_DEFAULT_MD_NID is documented to return 2 for a mandatory digest algorithm, when the key can't support any others. That isn't true here, so return 1 instead.
