> When server requires ssh-dss host key algorithm it is not possible to
> configure sFTP camel component to use such key type, therefore connecting
> fails with "com.jcraft.jsch.JSchException: Algorithm negotiation fail".
> When these two properties are added in debug mode:
> {code:java}
> session.setConfig("server_host_key", session.getConfig("server_host_key") +
> ",ssh-dss")
> session.setConfig("PubkeyAcceptedAlgorithms",
> session.getConfig("PubkeyAcceptedAlgorithms") + ",ssh-dss") {code}
> in SftpOperations class:
> !image-2022-07-11-10-34-58-099.png!
> the connection is established successfully.
> It should be possible to configure "server_host_key" and
> "PubkeyAcceptedAlgorithms" in camel sFTP component.
