SSH to Cisco ASA does not support sha1

I have issues connecting with SSH to my Cisco ASA firewall.

My SSH client (osx terminal) complains about sha1 that is the only key exchange hash method that the ASA supports. I cannot find any solution for it on the Cisco-side.

Any ideas?

Unfortunately there is no solution on the asa side at the moment. The only workaround is editing your ssh configuration on the client-side to accept sha1. I think we will see a solution to this in the near future but there is no public visible enhancement request at the moment that I am aware of.
