As a RSA-user myself, because I learnt about ssh through the github setup guides: Will ssh-keygen generate a secure key if I don’t pass it any parameters?

- RL_Quine 7y agoI haven't built the new version, but I assume it defaults to ed25519 now. You can otherwise make one with ssh-keygen -t ed25519.
- techntoke 7y agoLast time I tried AWS doesn't support anything but RSA keys.
- RL_Quine 7y agoThat’s right. Nothing stopping you having both though.
- zenexer 7y agoThey don’t need to. Boot up a default AMI, change the key to whatever you want, then create your own custom AMI from that. Or you can use something like Cloud-Init.
- lawnchair_larry 7y agoThis is good news, because AWS will finally be forced to get with the times. Their certificate manager is stuck on RSA too.
- jlgaddis 7y agoIt will generate a 2048-bit RSA keypair by default. It will be "a secure key" as long as you protect it with an appropriate passphrase.
- gnufx 7y agoYou need recent ssh-keygen's -o to make the passphprase effective (default for ed25519). That was covered here at some stage, but I don't have a reference.
