Matt Sicker commented on SSHD-1017: ----------------------------------- Oh yes, that makes sense. I read through the OpenSSH source code a lot while I was working on the AES/GCM extension here as well as attempting this extension, and it's written very cleanly (typical OpenBSD pride point), and I also looked through Dropbear which seems to have some popularity in the embedded and IoT space due to being even smaller than OpenSSH. I noticed that most SSH implementations are extremely similar (they're all built around the standard after all, and it does encourage specific architectures), so I hope that such an approach might be feasible anyways. In the meantime, though, this particular Jira ticket is still to support [chacha20-poly1...@openssh.com|mailto:chacha20-poly1...@openssh.com] and not some hypothetical [chacha20-poly1...@apache.org|mailto:chacha20-poly1...@apache.org] extension.
