title: J2SSH supported ciphers/Macs
body: <p>I am running a java application which uses J2ssh library to establish the connection to the server.
  Last week we migrated to a new IBM server</p>
  
  <p>Here the problem is we are unable to establish FTP/SFTP connection to the new server from my java application. But the connectivity is working fine from other tools.</p>
  
  <p>My doubt is whether the J2SSH library  will support the below ciphers/macs ? because these are the ciphers configured in the new IBM server.</p>
  
  <pre><code>Ciphers aes128-ctr,aes192-ctr,aes256-ctr,arcfour256,arcfour128
  MACs hmac-sha1,umac-64@openssh.com,hmac-ripemd160
  </code></pre>
