The content of the ssh public key is
ssh-ed25519 AAAAC3NzaC1lZDI1NTE5AAAAIEE98TW954KHCx7HFoEVVlTDMHnkodqcPsKj4bThfPZ8 me@home
When I try to import it, RouterOS says
unable to load key file (wrong format?) !
This is quite annoying, keeping an RSA key around literally just for my Mikrotiks now.
Currently only DSA and RSA keys are supported.
I would like to see support for ed25519 keys as well…
BTW, RSA is supported since RouterOS 6.31 and has been added after OpenSSH deprecated DSA in a way that you had to specify extra options to connect. Let’s hope we do not need a similar event for ed25519 keys. On the other hand RSA is still considered secure - in contrast to DSA.
