title: The cipher 'aes256-cbc' is required, but it is not available in java
body: <p>I am trying to establish SSH connection in java. I have openSSH private kek.ppk file and it has <strong>Encryption: aes256-cbc</strong> . When i try to load it in java, it throw <strong>com.jcraft.jsch.JSchException: The cipher 'aes256-cbc' is required, but it is not available.</strong></p>
  
  <p>I have searched this error with internet and find solution that we should convert that key file using <strong>putty key gen</strong>.</p>
  
  <p>But i want to use <strong>Encryption: aes256-cbc</strong> to establish SSH in java.</p>
