Why ED448?
It’s almost never recommended, in favor of curve 25519.
- stock_toaster 3y agoI believe ed25519 offers 128 bits of security, while ed448 offers 224 bits of security. ed448 has larger key sizes too, which does seem like an odd choice in this case. Maybe it was chosen for obscurity sake (being less commonly used)?
- throitallaway 3y agoAs I understand it Ed448 was only recently added to openssh, so maybe it was chosen in order to evade detection by analysis tools that scan for keys (if such a thing is possible.)
- juitpykyk 3y agoSome tools scan for crypto algorithms, typically by searching for the magic numbers, Ed448 is so new many tools probably don't recognize it. Malware authors frequently change the crypto magic numbers to prevent detection.
