I was testing against LibreSSL 2.9.2, the oldest for FreeBSD, and this particular call is listed in the OpenBSD 6.5 changelog here: https://www.openbsd.org/plus65.html "Provided SSL_get_client_ciphers() and SSL_get1_supported_ciphers() (part of the OpenSSL 1.1 API)." But I haven't figured out when or where this was added to LibreSSL releases. It really looks to me that there isn't a strategy for LibreSSL, but I'll not backport things to old LibreSSL version, the answer should be "upgrade or else leave it to your packager/distributor". _______________________________________________ Openvpn-devel mailing list Openvpn-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/openvpn-devel
