> Key: KARAF-3621
> URL: https://issues.apache.org/jira/browse/KARAF-3621
> Project: Karaf
> Issue Type: Improvement
> Components: karaf-shell
> Affects Versions: 3.0.3
> Reporter: Ancoron Luciferis
> Assignee: Freeman Fang
> Labels: security
> Attachments: karaf-3.0.x-Default-to-a-more-secure-SSH-host-key-configuration.patch

>
> By default, the Karaf SSH server generates a new 1024-bit DSA host key.
> As we've learned from the crypto specialists in the past few years, this is no longer seen as being a reasonably secure key pair generation algorithm.
> At the time of this writing, a reasonably secure key pair would be generated using RSA with a size of 4096 bits.
