5.1/5.2 - The suggested algorithm names are structurally different to
the other algorithm identifiers used in SSH. In particular, I don't see
any need for the "-ssh" to appear in the algorithm name as the cipher
has not been modified in any substantial way. Why not just "aes128-gcm"
or "aes128-gcm-aead" if you wanted to be particularly verbose?
AEAD has its own convention for naming algorithms. The names selected
are more in keeping with the AEAD conventions. I'm not terribly fond of
theses names and would be willing to modify them as needed, but I'd like
to keep an "ssh" tag in the name so that when one looks at the namespace
of all AEAD algorithms, it is clear that these algorithms are intended
for use in secsh.
