Dong Chen updated SPARK-13331:
------------------------------
Description:
In network/common, SASL with DIGEST-MD5 authentication is used for negotiating
a secure communication channel. When SASL operation mode is "auth-conf", the
data transferred on the network is encrypted. DIGEST-MD5 mechanism supports
following encryption: 3DES, DES, and RC4. The negotiation procedure will select
one of them to encrypt / decrypt the data on the channel.
However, 3des and rc4 are slow relatively. We could add code in the negotiation
to make it support AES for more secure and performance.
The proposal is:
When "auth-conf" is enabled, at the end of original negotiation, one more step
is added. If client is configured to support AES, it will send request to server
was:
