 Dear developers,

 Yes, I know this might sound absurd, but since PuTTY is handling 8192-bit
 private key very well, I think it would be good to see Cyberduck also
 support key size of 4096+.

 So, here are some details:[[BR]]
 I generated a new pair of key using my FreeBSD machine's bundled OpenSSH*:
 {{{ssh-keygen -trsa -b8192}}}. Then I imported the key into PuTTYgen,
 saved as PuTTY Private Key format.[[BR]]
 Now, PuTTY handles this very well; I can log into both FreeBSD and Debian
 machines I have. Even logging into each other using OS bundled SSH client
 was successful. Only Cyberduck is complaining about the key size. (I
 attached the complaint Cyberduck was quacking.)

 I hope to see Cyberduck supporting this soon. :)

 * {{{OpenSSH_6.6.1p1, OpenSSL 1.0.1p-freebsd 9 Jul 2015}}}
