Update SSH Host Key Ciphers and algorithms Sha-256/512

We are running Data Power Gateway appliances, these the supply the security we use for connectivity to all our trading partners, one trading partner that we connect with uses AWS and AWS have recently updated their security policy that now requires the use of more secure cipher/algorithms. AWS now require the use of rss-sha-256 and rsa-sha-512 hostkey algorithms. The issue is that Data Power does not currently support these, we have in this case been able to communicate with AWS to lower their requirement on security in this case as we just can not use those ciphers/algs.

The connection protocol in this particular use case was SSH, we connect to a growing number of AWS platforms and SSH is a very widely used protocol.

It seems silly to be asking IBM to add higher levels of security to an appliance that is meant for high levels of security. we also can not be asking AWS to break their security policies each time that we need to connect to a trading partner host in AWS.


These SSH ciphers/algorithms really must be updated.


Thanks
