=== ED25519

ED25519footnote:[https://datatracker.ietf.org/doc/html/rfc8709] is a relatively somewhat new OpenSSH key algorithm. It has numerous benefits over e.g. RSA, including:

* fixed key sizes, so fixed pubkey sizes
** and significantly shorter pubkeys, yet-
* strength comparable to RSA4096, but-
** much faster
* public domain and https://ed25519.cr.yp.to/[developed by independent researchers^]; not tied to specific corporation (i.e. nothing like https://en.wikipedia.org/wiki/RSA_Security[RSA^])

I recommend it over all other key types for new SSH keys as long as it's supported by clients/servers.
