#398: Cannot connect with SSH public key authentication ("Can't read key due to
internal IO problems")

     Type:  defect              |      Status:  new    
 Priority:  high                |   Milestone:         
Component:  sftp                |     Version:  2.5.5  
 Severity:  major               |    Keywords:

 Whilst trying to use SSH public key authentication to connect to a server,
 the following error is returned from Cyberduck:

  '''IO Error: Can't read key due to internal IO problems:
 java.io.IOException: Assertion failed, next byte value is f8 instead of
 asserted 30'''

 Cyberduck is able to connect normally (over SFTP) if password
 authentication is used instead of public key authentication.

 Private key is in format of
  -----BEGIN RSA PRIVATE KEY-----
  Proc-Type: 4,ENCRYPTED
  DEK-Info: DES-EDE3-CBC,4C69CBBC6918389F

 and is correctly selected inside my Cyberduck bookmark for the site to
 which I am attempt to connect.

 I would much prefer to connect via public key authentication (especially
 if Cyberduck support ssh-agent key forwarding!, but that's an enhancement,
 not a defect) but as of yet have been unable to connect via SFTP except
 with password authentication.
