SSH Key authentication fails when RFC4716 format Keys used

XMLWordPrintable

      Issue Summary

      When using SSH key authentication, a confusing error can appear in the UI or logs if the incorrect SSH key format is used.

      Example Steps to Reproduce

      1. Create an RSA SSH Key Pair using ssh-keygen 
        ssh-keygen -t rsa
      2. Add the Public Key to your Bitbucket Cloud account
      3. Upload the Private Key to a Linked Repository configuration
      4. Test the repository connection

      Expected Results

      The connection test is successful

      Actual Results

      The connection test fails, and the following exception is thrown in the UI:

      Cannot decode connection params.

      Notes

      This occurs when the version of OpenSSH has RFC4716 as the default key format.
      The SSHJ Library that Bamboo uses does not support the SSH2/RFC4716 keys.

      Workaround

      Create the key using PEM format, which RFC4716 replaced. For example:

      ssh-keygen -m PEM -t rsa
