Raw Blame History

From 87530e9ebc872761c06506f3cb6a4fa5c494a614 Mon Sep 17 00:00:00 2001
From: Stephen Gallagher <sgallagh@redhat.com>
Date: Tue, 7 Jan 2020 14:32:01 -0500
Subject: [PATCH 10/10] Better validation of command line arguments
Check that key passphrases are within 4-1023 characters
OpenSSL CLI tools cannot handle files with passphrases outside this
range.
Resolves: rhbz#1784441
Signed-off-by: Stephen Gallagher <sgallagh@redhat.com>
Output private keys with 2048 iteration count
Signed-off-by: Stephen Gallagher <sgallagh@redhat.com>
Rework passphrase handling
Handle passphrases as part of the sscg_stream for a file. This will
allow us to check for relevance as well as reducing code duplication.
Resolves: rhbz#1784443
Signed-off-by: Stephen Gallagher <sgallagh@redhat.com>
Fix wrong x509 version in CSR
This was, fortunately, not causing any problems because the signing
process resulted in the certificates being generated with the
correct version. It's best to be correct anyway.
Signed-off-by: Stephen Gallagher <sgallagh@redhat.com>
Fix memory leaks
Signed-off-by: Stephen Gallagher <sgallagh@redhat.com>
Fix alignment issue with popt
The boolean values need to be explicitly defined as int because
a bool may not be aligned properly. It was working prior to some
recent changes by lucky accident.
Signed-off-by: Stephen Gallagher <sgallagh@redhat.com>
Prevent uninitialized read error
Signed-off-by: Stephen Gallagher <sgallagh@redhat.com>
Add missing newline for error message
Signed-off-by: Stephen Gallagher <sgallagh@redhat.com>
Fix OpenSSL 1.0 support
The symbol UI_F_UI_SET_RESULT changed to UI_F_UI_SET_RESULT_EX in
OpenSSL 1.1, but no other semantics changed that we care about.
Signed-off-by: Stephen Gallagher <sgallagh@redhat.com>
Fix formatting
Signed-off-by: Stephen Gallagher <sgallagh@redhat.com>
Fix missing error check
Signed-off-by: Stephen Gallagher <sgallagh@redhat.com>
Read long password files properly
Long passphrase files may require more than a single call to BIO_read()
to gather the whole string.
