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 its supported by clients/servers.
