While the Diffie-Hellman key exchange may seem complex, it is a fundamental part of securely exchanging data online. As long as it is implemented alongside an appropriate authentication method and the numbers have been selected properly, it is not considered vulnerable to attack.

Is Diffie-Hellman more secure than RSA?

Can Diffie-Hellman be broken?

Regardless of the shared prime key issue, DH and RSA up to 1024-bit can be easily broken by the NSA. If you’re not already using 2048+ bit keys (DH/RSA) or ECC 256-bit, you’re doing it wrong.
