title: Gitkraken hates my SSH keys, that work in SourceTree
body: <p>I'm connecting to a private git repository, one which I've been using fine with SourceTree for years.</p>
  
  <p>I'm trying to work with GitKraken since SourceTree is getting increasingly slow, and GitKraken tells me my key pair is "invalid" and I need to check if they are in RSA format.</p>
  
  <p>The key pair was generated by Putty Gen and works fine for SourceTree and other formats.  I even tried reopening them in PuttyGen and exporting in RSA format, no difference.</p>
  
  <p>Any idea why?  I suspect it's some kind of formatting issue, but it's hard for me to tell and GitKraken has zero documentation on this error.</p>
  
  <p>Thanks in advance.</p>
