From 1f992f9a857346b8837fd12d8c90f7b2cafb9613 Mon Sep 17 00:00:00 2001 From: Robbie Harwood Date: Tue, 26 Mar 2019 18:51:10 -0400 Subject: [PATCH] [downstream] Remove 3des support Completely remove support for all DES3 enctypes (des3-cbc-raw, des3-hmac-sha1, des3-cbc-sha1-kd). Update all tests and documentation to user other enctypes. Mark the 3DES enctypes UNSUPPORTED and retain their constants. Last-updated: 1.21.1-final [antorres@redhat.com: remove diffs for: - src/kdamin/testing/proto/kdc.conf.proto - src/lib/kadm5/unit-test/api.current/chpass-principal-v2.exp - src/lib/kadm5/unit-test/api.current/get-principal-v2.exp - src/lib/kadm5/unit-test/api.current/randkey-principal-v2.exp since they were removed by Remove-TCL-based-libkadm5-API-tests.patch] [jrische@redhat.com: restore supportedCMSTypes (not using 3DES any more): -
