[resolved] tFTPComponent Invalid Private Key Error

Hi,
Our team is using the Talend Big Data Platform 6.2 on Windows 7. When I use the tFTPComponent I get an error that says "tFTPConnection_1 invalid privatekey: [B@80503" when it tries to connect to the remote server. It shows the sFTP options because I clicked the SFTP Support check box.
We do have a id_rsa key in a local drive that it is using.
My question is: is there some kind of speical key format that the Talend tFTPConnection? Does it need to be in any special encoding?
The funny thing is that this key works fine when we use sFTP directly to connect, just not when we try to connect using Talend.
More info

It turns out that we were able to get the sftp to work after generating the key with this command 
ssh-keygen -t rsa
Previously we used a -o switch but that seemed to cause the "invalid private key" in Talend.

Hi,
Did you use putty keys? If so, need to be converted to open ssh keys.
Could you please take a look at this related forum:https://www.talendforge.org/forum/viewtopic.php?id=8662 to see if it works?
Best regards
