ssh-keygen(1): generate Ed25519 keys by default. Ed25519 public keys

Finally!

• ssh(1): add keystroke timing obfuscation to the client. This attempts to hide inter-keystroke timings by sending interactive traffic at fixed intervals (default: every 20ms) when there is only a small amount of data being sent. It also sends fake “chaff” keystrokes for a random interval after the last real keystroke. These are controlled by a new ssh_config ObscureKeystrokeTiming keyword.

Interesting! I wonder if there was some concept sniffer to guess the password.
