Subject: [PATCH] disable obsolete and unused ciphers in Apache SSL configuration
Date: Mon, 04 Sep 2017 19:34:52 +0200 [thread overview]
Message-ID: <20170904193452.485039d4.peter.mueller@link38.eu> (raw)
[-- Attachment #1: Type: text/plain, Size: 1963 bytes --]
Perform these modifications to the Apache SSL cipherlist:
- disable unused suites (SRP, DSS, PSK)
- disable DH, DHE and EDH suites (slow and rarely used, vulnerable to LOGJAM)
- prefer ECDSA over RSA
- prefer suites with PFS over those without
- only allow listed cipher suites (makes the list a bit shorter)
This fixes bug #10856.
