Issue:
SFTP Uprocs using advanced/new protocols for key pairs exchange are not working in Dollar Universe. The same keys do work outside of DollarU.

This concerns for instance, but not exclusively, rsa 4096 or Diffie–Hellman keys

The following error is displayed in the job log:
* Connected to <partner> port 22 (#0) 
* User: <user>
* Password: 
* SSH socket: 0 
* Failure establishing ssh session 
* Closing connection #0 
* Failed initialization 
Cause:
Dollar Universe was compiled with libssh2 version 1.4.1
Resolution:
