Does Boomi support SSH2 for SFTP ?
Boomi does support SSH2 as our connector is based on JSch library, but is requires customer to install its dependcy - "JavaTM Cryptography Extension (JCE)"
Also, would I be correct to say that you are testing this process using the 'boomi-molecule'?
If so, please install the JCE Unlimited Unlimited Strength Jurisdiction Policy Files on this molecule. Details for the installation are in the following reference guide link. Please let me know if you have any questions.
