SSHJ provider - private/public key authentication using Credential Store

Current Situation

• When YADE is configured to use the following settings:
  • ssh_provider=sshj
  • SSH private/public key authentication using a Credential Store with a setting such as AuthenticationFile=cs://@attachment
• then the following error occurs if the private key is used from an attachment of the KeePass Credential Store database:

  com.sos.JSHelper.Exceptions.JobSchedulerException: Exhausted available authentication methods
  

Desired Behavior

• SSHJ provider - private/public key authentication using Credential Store should work when used with a setting such as AuthenticationFile=cs://@attachment

Maintainer Notes

• The underlying sshj library supports the following private key file formats when a private key file is used from the file system:
  • pkcs5, pkcs8, openssh-key-v1, ssh-rsa-cert-v01@openssh.com, ssh-dsa-cert-v01@openssh.com
• When a private key is used from a KeePass Credential Store database:
  • currently private key files with the pkcs8 format only are supported. This is the format used by OpenSSH.
