Web11 de fev. de 2013 · 1. OpenSSL is a set of tools and libraries. The applications that offer TLS encrypted services use those libraries (unless they use gnutls or Java libraries, which are also not uncommon). The ciphersuites are implemented in those libraries. If you need newer ciphersuites, you have to update the library. Web5 de jul. de 2015 · You can pass multiple ciphers using a space, comma or colon separator. Example: openssl s_client -cipher ECDHE-RSA-AES256-SHA:ECDHE-RSA-AES256-GCM-SHA384 \ -connect example.com:443. The above list specifies two specific ciphers. A group of ciphers can also be passed.
