Hello,

I have some issues with loading Putty private key files if the comment section contains umlauts (äöü). No matter if the key is encrypted or not, i get the same results:

If there are no umlauts, it just works fine:

--fromPuttyPrivateKey
    Success.
  --FromPuttyPrivateKey
--ChilkatLog

My sample code:

Dim key = New Chilkat.SshKey()
key.VerboseLogging = True
If Not key.FromPuttyPrivateKey(key.LoadText(FileName)) Then
  Debug.WriteLine(key.LastErrorText)
End If

Same result with (to make sure a different encoding doesn't do the trick):

Dim key = New Chilkat.SshKey()
key.VerboseLogging = True
If Not key.FromPuttyPrivateKey(New StreamReader(FileName, System.Text.Encoding.Default).ReadToEnd) Then
  Debug.WriteLine(key.LastErrorText)
End If

Did someone encounter the same problems? Thanks in advance!

Kind regards
