Cool project! Note that from the encodings currently implemented in Edky, OpenSSH's encoding is the most complicated to encode/decode. If anybody would need to be working with your public keys and signatures outside your own code base, I'd suggest the simplest would be to keep to hexadecimal or Base64(Url).

Thanks for the appreciation and the tip! I'll keep an eye on edky!

Asfaload is easy to selfhost, if it is of any interest to you.
