I am looking for a way to limit asterisk TLS negotiation ciphers.
When I run “pjsip list ciphers” I see a lot of cipher but I want to block all negotiontions with cipher RC4.
When I put only one cipher to transport config
it still response to connect attempts with RC4 cipher ;
openssl s_client -connect localhost:8089 -tls1 -cipher RC4-SHA
New, TLSv1/SSLv3, Cipher is RC4-SHA
Server public key is 2048 bit
Secure Renegotiation IS supported
I am looking for a solution. Would you please advise a way to achieve it.
