Adding additional Key Exchange Algorithms for SSPCM

Problem Description:-
We are trying to add the following key exchange algorithm(group-exchange-sha256)in B2B through customer overrides properties file like as below.
security.SSHKeyExchangeAlgList=diffie-hellman-group-exchange-sha1,diffie-hellman-group1-sha1,diffie-hellman-group14-sha1,group-exchange-sha256

But it is not supporting.Ref:-http://www-01.ibm.com/support/docview.wss?uid=swg22000009

the following items had to be added to the list of supported Key Exchange Algorithms in the SSPcm definitions for both the SFTP Adapter security settings and the SFTP outbound node security settings.

• diffie-hellman-group-exchange-sha1
• diffie-hellman-group1-sha1
• diffie-hellman-group14-sha1

The problem appears to be that SFG/B2B does not support the Aviva approved algorithm of “group-exchange-sha256”.

We are requesting to consider this request and add the above cipher in the upcoming B2Bi release.
