I've built libssh2 with wincng and have been testing with the CrushFTP server. All has been working smoothly. In trying to install my software at a client site, they are attempting to use AWS SFTP service. When performing the libssh2_session_handshake I am failing with a KEX error.

A log from the server indicates:

Mar 25 13:58:14 pathlabsrv sshd[4988]: fatal: no matching cipher found: client aes256-cbc,rijndael-...@lysator.liu.se,aes192-cbc,aes128-cbc,arcfour128,arcfour,3des-cbc server aes128-ctr,aes192-ctr,aes256-ctr,aes128-...@openssh.com,aes256-...@openssh.com,chacha20-poly1...@openssh.com [preauth]

And, indeed, we do not have a matching cipher. I would have expected Windows cryptography to be generally 'vanilla' and I would have expected Amazon to support pretty much anything. From my limited experience they seem to have used Open SSH.

Has anyone encountered this? Can anyone give me guidance?

Subject: RELEASE: libssh2 1.8.2

Hi!

I'm happy to announce a small update to the previous release as we managed to
get a little hiccup included. Here's 1.8.2!

Get it from https://www.libssh2.org/ as always!

libssh2 1.8.2

This release includes the following bugfixes:

 o Fixed the misapplied userauth patch that broke 1.8.1
 o moved the MAX size declarations from the public header

This release would not have looked like this without help, code, reports and
advice from friends like these:
