Azure Application Gateway - new TLS policy without RSA key-exchange

Good morning,

As you might know RSA key-exchange is becoming less and less popular. The reason for this being the lack of Perfect Forward Secrecy.

I was wondering if Microsoft Azure would consider releasing new TLS policy eliminating the RSA key-exchange ciphers from the cipher suite list. I know these can be customized but feel like this is something Microsoft might consider offering as a new version.

Suggestion for the updated AGW TLS Policy (changes vs AppGwSslPolicy20170401S):

  • Remove ciphers with RSA key-exchange
  • Add support for ciphers containing CHACHA20_POLY1305 bulk encryption

Thanks for considering.

Best regards,
Max
