From 2f6529d9dc8aa82eb5bdcccec9c69d93dad63505 Mon Sep 17 00:00:00 2001 From: Mark Hatle Date: Thu, 25 Feb 2016 09:49:57 -0600 Subject: rpm: Enable specific crypto and digest settings via variables Allow the user to set the specific digest and non-repudiable signature algorithms. This should be done on a distribution wide basis. See recipe for exact instructions, but values are now set using: RPM_FILE_DIGEST_ALGO (default 1 - md5) RPM_SELF_SIGN_ALGO (default DSA) Also, change the PACKAGECONFIG to define the default crypto engine for RPM5. Not just the available crypto engines. If a crypto engine is not selected, the system will default to the internal beecrypt version.
