Hey! No ed25519.

The original SSH2DOS implementation is from a putty version from around 2005. The parts I added/updated are from 0.70 (from 2017). Other ciphers etc from that version would be relatively easy to be added to this project. Anything after that version would more or less require a big rewrite.

I haven't forgotten about this project and I'm hoping to have some time to spend on it again.

Longer term better solution would be to do a new, full port of the latest putty. One day!
