5 TopicsCustom cihper suite for ClientSSL Profile
Hello Folks, I want to use a custom set of ciphers in my ClientSSL Profile. I have gone through the document of F5, how can disallow ciphers by putting ! However I have a requirement that I need to use only 2 cipher suites such as AES128-SHA256 & AES256-SHA256 and rest should be deny. How can I deny remaining cipher suites by allowing only the required one? Any help is appreciated. Cheers! Darshan431Views0likes8CommentsCipher Suite: Disable DHE / EDH?
Hi does somebody know how to disable DHE/DSS and EDH/RSA KeyX Algorithms?

Hi, A novice here. As per recent OpenSSL report, RSA ciphers are being termed as weak. E.g.: TLS_RSA_WITH_AES_256_GCM_SHA384 However ECDHE with RSA still stay strong. E.g.: TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384 Is there a way to update my cipher string which would block RSA ciphers but not ECDHE RSA ones? Thanks.261Views0likes2CommentsDefault SSL Cipher Suite Reorder
In 11.4.1, does anyone know the syntax of the Ciphers field if we want to reorder the DEFAULT order? The DEFAULT order is RC4-SHA, AES128-SHA, AES256-SHA, DES-CBC3-SHA, AES128-SHA256, AES256-SHA256, ECDHE-RSA-AES128-CBC-SHA, ECDHE-RSA-AES256-CBC-SHA, ECDHE-RSA-DES-CBC3-SHA. What is the syntax if want to reorder to have RC4-SHA last and put the ECDHE suites first?Solved515Views0likes2Comments
