SSL certificate supports Weak Ciphers/Encoding (3DES) (Apache 2.4)

• SSL Medium Strength Cipher Suites Supported (SWEET32) [TOMCAT server]
• The remote host uses weak cipher encryption for communication.
• Where SWEET32 is also called 3DES / Birthday attack.

To verify use below OpenSSL command:

If the OpenSSL is connected to the host at SSL port & we received the response with the certificate then it's having weak cipher suites.

• openssl s_client -connect Hostname:443 -cipher ""DES:3DES"" -tls1_2
• openssl s_client -connect Hostname:443 -cipher ""DES:3DES"" -tls1_1
• openssl s_client -connect Hostname:443 -cipher ""DES:3DES"" -tls1

SSLCipherSuite having strong cipher enabled, and to disable/restrict weak cipher using !DES:!RC4:!3DES:!MD5:!PSK

File Name: ssl.conf / httpd-ssl.conf
