[PATCH 0/3] sign-file,extract-cert: switch to PROVIDER API for OpenSSL >= 3.0

[Jan Stancek <jstancek@redhat.com>]

The ENGINE interface has its limitations and it has been superseded
by the PROVIDER API, it is deprecated in OpenSSL version 3.0.
Some distros have started removing it from header files.

Update sign-file and extract-cert to use PROVIDER API for OpenSSL Major >= 3.

Tested on F39 with openssl-3.1.1, pkcs11-provider-0.5-2, openssl-pkcs11-0.4.12-4
and softhsm-2.6.1-5 by using same key/cert as PEM and PKCS11 and comparing that
the result is identical.

Jan Stancek (3):
  sign-file,extract-cert: move common SSL helper functions to a header
  sign-file,extract-cert: avoid using deprecated ERR_get_error_line()
  sign-file,extract-cert: use pkcs11 provider for OPENSSL MAJOR >= 3
