(313/314) 3615137 - Can't use SSH keys from puttygen on Windows FtpPlugin

My private key is not supported by the ftp plugin, the 1.0.3 or the trunk fails with it.
It says
14:03:43 [jEdit Worker #3] [error] ListDirectoryBrowserTask: java.io.IOException: com.jcraft.jsch.JSchException: The cipher 'aes256-cbc' is required, but it is not available.

The key was generated with puttygen

See related ticket: https://sourceforge.net/tracker/?func=detail&aid=3614769&group_id=588&atid=565475
current workaround is to generate your keys from linux with ssh-keygen.

You may close this. I already forgot about it. The key wasn't generated with puttygen but on a Solaris box.

I don't know, what the problem was but in the meantime it's working.

I assume the previous comment was related to #3611815 and closed that ticket as you suggested.

matthieu, what if you create a 1024 bit DSA key with puttygen and use that? Do you still have the same problem?
The macOS issue seems to only happen for certain kinds of keys but not every kind.

oh actually, that error seems to be related to you missing the JCE strong encryption package.
My guess is that if you install JCE unlimited strength encryption into your JRE, this will be resolved, but there is nothing that can be done from the FTP plugin. See Chapter 1 of the FTP documentation for the link to JCE unlimited encryption.
