ED25519

ED25519^[1] 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 developed by independent researchers; not tied to specific corporation (i.e. nothing like RSA)

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