Greetings, I'm using OpenSSL for testing and recently compiled 1.1.0g and h. I'm seeing the same behaviour in both.
openssl ciphers -v list the NULL ciphers, but when I try to use NULL or NULL-MD5 I get the same result: No ciphers available. I've tried several compile options to no avail. Can anyone point me in the right direction? Thanks! ./openssl s_client -connect x.x.x.x:443 -cipher NULL CONNECTED(00000003) 140735917126464:error:141640B5:SSL routines:tls_construct_client_hello:no ciphers available:ssl/statem/statem_clnt.c:800: --- no peer certificate available --- No client certificate CA names sent --- SSL handshake has read 0 bytes and written 0 bytes Verification: OK --- New, (NONE), Cipher is (NONE) Secure Renegotiation IS NOT supported Compression: NONE Expansion: NONE No ALPN negotiated SSL-Session: Protocol : TLSv1.2 Cipher : 0000 Session-ID: Session-ID-ctx: Master-Key: PSK identity: None PSK identity hint: None SRP username: None Start Time: 1522278574 Timeout : 7200 (sec) Verify return code: 0 (ok) Extended master secret: no --- -- Eric Jacksch, CPP, CISM, CISSP +1 613 482-7650 e...@jacksch.com Twitter: @EricJacksch https://SecurityShelf.com <https://securityshelf.com/>
