Status: NEW
Severity: enhancement

--> https://bugzilla.mindrot.org/attachment.cgi?id=3918&action=edit
screen shot of the kex algorithms
The kex algorithm proposal from the sftp server starts with a comma or
has consecutive commas in the proposal strings.
I have attached the screen shot and network traces where this was
captured. this issue is not always reproducible but when it happens it
causes the client to hang.
I have already contributed the fix for the client, Kindly check and fix
this issue from the server side.
