Hello, My program is unable to open a Net::SFTP connection because Net::SSH::Perl::Cipher::Chacha tries to load Crypt::OpenSSH::ChachaPoly, which doesn’t seem to exist within CPAN, and fallback to other ciphers is not happening.

Thanks for your report. I once uploaded lkinley's version to CPAN but it made Net::SSH::Perl fail (in the tests IIRC). So I removed it again because I don't really have knowledge on the topic itself and couldn't rank the impact. You could try http://renormalist.net/misc/Crypt-OpenSSH-ChachaPoly-0.02.tar.gz which is the tgz I built back then 2016-05-09 from https://github.com/renormalist/Crypt-OpenSSH-ChachaPoly and report here if that helps you. In my case it did not. If you have time to dive deeper into it it would help if you can provide details, patches, etc. In particular, lkinley also seems to have a new version 2.04 in his github repo which I didn't yet uploaded to CPAN but should probably do (lkinley's repo just lacks some CPAN polishing which I usually contribute). However locally it could be installable for you with some perl Makefile.PL; make; make test; make install. I hope that helps you a bit further.

Thanks much for rapid response. Until it can be added back to CPAN, it seems like the attempt to load Crypt::OpenSSH::ChachaPoly should be removed, or code should be adjusted so fallback works.

I just re-uploaded Crypt::OpenSSH::ChachaPoly to CPAN. This means this issue here is probably be back as described. Let's see what cpan testing reveals... Kind regards, Steffen On Fri Jun 17 12:44:37 2016, bracdt@gmail.com wrote: Show quoted text

I just created https://github.com/lkinley/Net-SSH-Perl/issues/5 on lkinley's github repository because he is doing his current work there. Unless I mixed up things, that ticket should be related to this RT ticket here. Feel free to watch progress there or follow up on questions. Thanks for your report.

Hi, can you please try if the just uploaded v2.12 fixes this issue? As I'm just doing the CPAN uploads based on Lance Kinley's work at https://github.com/lkinley/Net-SSH-Perl I need your help on verifying this. Thanks, Steffen On Thu Oct 13 18:22:27 2016, SCHWIGON wrote: Show quoted text
