Hi Mathias,
Thank you for your feedback!
There is C library implementation already available: newbielink:https://www.libssh.org/ [nonactive] with following features:
SCP and SFTP support (client and server)
Support for Linux, BSD, Solaris and Windows
Client and Server implementation
Kerberos support (GSSAPI)
OpenSSL and GCrypt
Public Key infrastructure
Elliptic Curve DSA (ECDSA) support (with OpenSSL)
Elliptic Curve Diffie Hellman (ECDH) support
Asynchronous (non-blocking) support
Probably it might help to reduce the implementation time. Not sure if I would be able to build the plugin myself.
Regards,
Nick
