Goldstein Lyor resolved SSHD-759.
---------------------------------
       Resolution: Won't Fix
    Fix Version/s:     (was: 1.5.0)

This class has very specific functionality detailed in its Javadoc - it is not 
intended to be used in production code that wants to be as much as possible 
compliant with _OpenSSH_ current practices and provided as a courtesy for quick 
prototyping. It is a very old class and we are considering deprecating it since 
its behavior does not conform to any current practice.

> Should not overwrite existing ssh key if the algorithm does not match

>                 Key: SSHD-759
>                 URL: https://issues.apache.org/jira/browse/SSHD-759
>             Project: MINA SSHD
>          Issue Type: Bug
>    Affects Versions: 1.4.0
>            Reporter: Christian Schneider

> Currently a key file that does not have the correct algorithm is simply 
> deleted.
> I think this is not a good behaviour as the user might have created the key 
> explicitly.

> I propose we simply throw an exception if the algorithm does not match. Then 
> the user can decide if he wants to delete the file or change the algorithm.
