>             Project: Guacamole
>          Issue Type: Improvement
>          Components: guacd-docker

> The version of libssh2 within CentOS 7 lacks support for the more-recent versions of SSH key exchange methods and MACs. As the [guacamole/guacd Docker image|https://hub.docker.com/r/guacamole/guacd/] uses CentOS 7, it also lacks this support.
> Currently, the following key exchange methods are supported:
> * diffie-hellman-group14-sha1
> * diffie-hellman-group-exchange-sha1
> * diffie-hellman-group1-sha1
> and the following MACs are supported:
> * hmac-sha1,hmac-sha1-96
> * hmac-md5,hmac-md5-96
> * hmac-ripemd160
> * hmac-ripemd160@openssh.com
> More recent libssh2 includes support for SHA2 and curve25519. See https://wiki.mozilla.org/Security/Guidelines/OpenSSH for more information and references.
