URL: https://github.com/apache/mina-sshd/issues/483
We need to connect many SFTP servers and some SFTP servers are still using `
ssh-dss` algorithm for SFTP connection.
We have to use MuleSoft SFTP connector which internally uses
`sshd-core-2.12.1` library, by default ` ssh-dss` algorithm are disabled
because it is too weak to considered.
I'm able to communicate with these ssh-dss enabled SFTP servers using the
settings below. However, I'm unable to apply the same settings in the MuleSoft
SFTP connector because we can't modify their library.
```
sshClient.setKeyExchangeFactories(NamedFactory.setUpTransformedFactories(false,
BuiltinDHFactories.VALUES, ClientBuilder.DH2KEX));
sshClient.setSignatureFactories(new ArrayList<>(BuiltinSignatures.VALUES));
```
Could someone please advise if there's a method to enable the ssh-dss
algorithm via system variable settings? This would allow us to connect to
ssh-dss enabled SFTP servers without any code modifications.
