From c93d780442052ae113871f4033d788a5bbe288fa Mon Sep 17 00:00:00 2001
From: Ken Goldman <kgoldman@us.ibm.com>
Date: Mon, 23 Aug 2021 16:09:41 -0400
Subject: [PATCH 1/7] utils: Update certifyx509 for Openssl 3.0.0
i2d_x509 no longer accepts a partial structure. Therefore, replace
the input and output parsers with the ASN.1 parsing macros.
Eliminated the custom DER parsing. Set the version from the TPM
output rather than hard coding to v3.
Add x509 validity time compatibility functions to cryptutils.c
Add -check_ss_sig to the regression test because openssl verify does
not verify the signature on self signed certificates.
Signed-off-by: Ken Goldman <kgoldman@us.ibm.com>
