I have a weird thing happening. We have the newest CrushFTP ( as of 20160802). And if I use PuttyGEN (as recommended here) . to create a standard 4k RSA-2 SSH key without a password, and try to use iit for password-less authentication. It shows this error in WinSCP (Version 5.9). And below that is the crush logs. Does anyone have a idea what I'm doing wrong?.
BTW It works like a champ if I create a 2k RSA-2 key.
The reason I am asking is we have a customer using a 4096 bit key that is standard with a lot of clients and its not working for us.

Do you have the java policy files installed to allow for strong cryptography?
Set the prefs, logging, debug level to 2. What is logged in the crush log during just this attempted login?
Email us directly at support so we can setup a GoToMeeting to look at this.
