[GitHub] mina-sshd pull request #31: Allow SSH 1.99 in addition to 2.0 for SSHD

[nu11ptr]

GitHub user nu11ptr opened a pull request:

https://github.com/apache/mina-sshd/pull/31

Allow SSH 1.99 in addition to 2.0 for SSHD

Several versions ago, SSH 1.99 support was added to the client to allow it 
to connect to Cisco devices. I'm now proposing the same be done to allow Cisco 
devices still using 1.99 to connect to SSHD.

You can merge this pull request into a Git repository by running:

$ git pull https://github.com/nu11ptr/mina-sshd master

Alternatively you can review and apply these changes as the patch at:

https://github.com/apache/mina-sshd/pull/31.patch

To close this pull request, make a commit to your master/trunk branch
with (at least) the following in the commit message:

This closes #31


commit f105ac9c82bb32ae3a8f064ca19caeb7aed4d94b
Author: Scott Meeuwsen 
Date:   2017-05-26T18:36:57Z

Allow SSH 1.99 in addition to 2.0

> It seems that if the SSHD client is using an _ed25519_ identity or the SSHD 
> server presents an _ed25519_ key, then the generated signature is wrong
