Description

Improve the security of Lavoisier for Diffie-Hellman (DH) key exchange parameters .

Diffie-Hellman key exchange is a popular cryptographic algorithm that allows Internet protocols to agree on a shared key and negotiate a secure connection. It is fundamental to many protocols including HTTPS, SSH, IPsec, SMTPS, and protocols that rely on TLS.

If you have a web or mail server, you should disable support for export cipher suites and use a 2048-bit Diffie-Hellman group.
