1 # TLS server: general ops and certificate extractions
4 # Very early (unsure when) GnuTLS prefers RSA auth by default. Later, but before 3.6.x, prefers
5 # ECDSA but the client can be given a priority order to override that. We're running the server
6 # with no priority string given (tls_require_ciphers) hence default, and with both types of
7 # server cert loaded (RSA first, though we don't document that as relevant and in testing it
8 # does not appear to matter).
10 # GnuTLS 3.6.5 appears to ignore the client priority ordering, always choosing ECDSA if both
11 # are permitted, if TLS1.3 is permitted, so we limit to TLS1.2.

15 # Have the client do RSA (but support ECDSA as well). That should get us RSA on both older and newer GnuTLS.
