TLS/SSL Version Test Tool

There are many free tools available to validate application security.

​

Example: openssl is inbuild tool to initiate the connection with specific protocol (sslv1,tls1.0, etc), this will helpful if your application is only expose to internal/intranet network.

​

Other free one Qualys ssl test., This will helpful to initiate all typen of test infact browser compatibility.

Hope this will help.​

Hi Korai,

To test Ciphers you can use Wireshark to check the "Server Hello" as below to know F5 selected which ciphers from client cipher list negotiation or you can use a command in as below.

[root@lb2:Standby:In Sync] config # openssl s_client -cipher 'ECDHE-RSA-AES256-GCM-SHA384' -connect 192.168.148.184:443

Cipher suites are configured per SSL Profiles(Client/Server), you need to type "TLSv1_2" in cipher strings as seen below to only support TLSv1_2 ciphers.

You can also check via CLI by typing command to check TLSv1.2 support ciphers only as below.

[root@lb2:Standby:In Sync] config # tmm --clientcipher TLSv1_2

testssl is good for testing without external access. https://testssl.sh

Usually use nmap or openssl for internal sites and Qualys SSL Labs for external sites.

Sample NMAP Command

nmap -sV -p 443 --script ssl-cert,ssl-enum-ciphers <host>

Thanks, Let me see how its goes

You can also test ciphers, versions and certs against NIST 800-52R2  at https://tlscompliance.trustfour.com.
