Resolution: Fixed
NIFI-8523 added properties for cipher and key algorithms in SFTP processors.
> Enable options for sftp connections (the "-o" parameter for sftp command line)
> ------------------------------------------------------------------------------

> Key: NIFI-7709
> URL: https://issues.apache.org/jira/browse/NIFI-7709
> Project: Apache NiFi
> Issue Type: New Feature
> Affects Versions: 1.11.4
> Environment: software platform
> Reporter: Kevin kapfer
> Priority: Minor
> Fix For: 1.14.0
>
>
> When the sftp server requires a different algorithm (for example dss) than
> available from NiFi UI's server, you get
> {code:java}
> Unable to negotiate with {server ip} port 22: no matching host key type
> found. Their offer: ssh-dss{code}
> for a response when invoking sftp from the command line. To connect
> successfully, you must provide:
> {noformat}
> -oHostKeyAlgorithms=+ssh-dss{noformat}
> to the command.
> The requested feature is to enable an option to specify the algorithm as an
> option, within the processors making sftp connections: GetSftp, PutSftp,
> FetchSftp, ListSftp.
> A possible workaround is to add the missing algorithm to the server's ssh
> configuration
