X. Note: The key in a Diffie-Hellman key generation process is static (long term); this differs from an ephemeral (temporary) key that you’ll find in the Diffie-Hellman ephemeral key generation process. x. TLS/SSL Server is enabling the BEAST attack. The server chooses the cipher to use based on the preference order and what the client supports. So, use the new version of TLS to enable use of stronger ciphers. crt and an encrypted private key named pkcs12_crt_key_encr_url. TLS/SSL Server Supports The Use of Static Key Ciphers.
