This script improves your security by setting the "Diffie-Hellman" key exchange to a minimum of 2048 bits. This is a secure way to exchange keys over public networks. This script only affects the SSL/TLS handshake process. The SSL/TLS handshake is a key part of establishing a secure connection over the internet. By disabling this weak algorithm, the script improves the security of the connection. By default, modern Windows versions use a 2048-bit size for Diffie-Hellman key exchanges. Sizes ...
