CF18 cfftp invalid privatekey

Hi there,

I am new to cfftp secure="yes" and  I keep getting invalid privatekey error and couldn't find anything when I google it.  I know the key is working as I can connect using filezilla.  So I had a look at the stack trace and google Jsch invalid privatekey and bam, found out I need to convert the key to "classic" OpenSSH format as per:

Just putting this out there in case a newbie come across the same problem.
