How to check the SSL/TLS Cipher Suites in Linux and Windows Tenable is upgrading to OpenSSL v1.1.1 across Products. The product line is migrating to OpenSSL v1.1.1 with product releases: Agent 7.5.0, Nessus 8.9.0, Tenable.sc 5.13.0, NNM 5.11.0, LCE 6.0.3. Due to the retirement of OpenSSL v1.0.2 from support. THIS IS WRONG. The second column in ciphers -v is the minimum version for the ciphersuite; since TLSv1.0 and 1.1 don't add any ciphersuites not present in SSLv3, in 1.0.1 and 1.0.2 this lists only SSLv3 and TLSv1.2 even though 1.0 and 1.1 are supported. In OpenSSL this master_secret is kept within the SSL Session SSL_SESSION. The initial handshake can provide server authentication, client authentication or no authentication at all. Default usage in HTTPS is to verify server authenticity with trusted Certificate Authorities known by the browser.

The openssl command line utility has a number of pseudo-commands to provide information on the commands that the version of openssl installed on the system supports. The pseudo-commands list-standard-commands , list-message-digest-commands , and list-cipher-commands output a list of all standard commands, message digest commands, or cipher socat stdio openssl-connect:zmap.io:443,method=sslv3 socat requires OpenSSL's libssl and libcrypto for SSL support, wget and curl require either OpenSSL or GnuTLS. zmap.io is a security related site that has SSLv3 disabled, Otherwise, in a pinch you can do this with bash (and a little suspension of disbelief). Take a minimal SSlv3 "client hello
