How to implement aes{128,256)-gcm at openssh.com.

[Jakub Jelen]

Hi,
you can use the example from libssh, but note that it is using the
"external counter" as at the time of implementing this, there was not
the new API to allow "internal counter", which should be more
straightforward using functions gcry_cipher_geniv() and
gcry_cipher_setup_geniv() -- not sure if they are in any released
versions yet already.

If you will have any specific questions, please let me know.

Regards,
Jakub
