If you used openssl dhparam -out dhparam2048.pem 2048 to generate a new pair you can use openssl dhparam -noout -text -check -in dhparam2048.pem to read and print that file in text mode. You will have to copy and paste the text into the Java security properties (using tr -d ':' to remove the : between the openssl hex representation) Diffie-Hellman is used in SSL/TLS, as "ephemeral Diffie-Hellman" (the cipher suites with "DHE" in their name; see the standard).What is very rarely encountered is "static Diffie-Hellman" (cipher suites with "DH" in their name, but neither "DHE" or "DH_anon"): these cipher suites require that the server owns a certificate with a DH public key in it, which is rarely supported for a variety of ... The Diffie-Hellman key exchange was one of the most important developments in public-key cryptography and it is still frequently implemented in a range of today’s different security protocols.. It allows two parties who have not previously met to securely establish a key which they can use to secure their communications. A security audit I just ran turned up that we are using a sub-par key strength (recommended 2048 or higher, ours is 1024 bits) for the Diffie-Hellman groups (TLS). Upon researching I found that starting JDK 8 we can set the DH key size to be 2048. Diffie Hellman Key Exchange. But, there’s another problem. Since F5 Big-IP doesn’t implement 2048-bit DH key exchanges yet becuase it doesn’t need to due to how it rotates it’s keys, we’ll need to disable all DHE cipers, or our grade will get capped to B, again. This is a limitation to the SSL Labs test, it can’t test the key ...
