You also have the option of using Thomas Hruska's Win32-OpenSSL at https://slproweb.com/products/Win32OpenSSL.html. Thomas makes 1.0.2a available for download on his site. Not useful! Those are default builds with SSL3 enabled. The suggestion was to buildOpenSSL with the unwanted features

I would like to disable SSL3 (to prevent POODLE attacks), but I would like to leave TLS1 enabled (particularly DES-CBC3-SHA, AES128-SHA and AES256-SHA). However disabling SSL3 with !SSLv3 disables TLSv1 also. Furthermore, disabling SSL3 with -SSLv3 then adding in individual ciphers such as

Hi, Some time back, to fix POODLE, I tried to fix with cipher suite, but still I can use the the protocol SSLv3. The server responds with openssl s_client -connect ip:port -ssl3 So The fix should come using SSL_CTX_set_options. I understand since you are using the compiled binary, you may not be
