I can’t add ssh key, I used ssh-keygen, but digitalocean says key invalid type

I ran ssh-keygen on my local machine from windows 10.

C:\Users\Dell>ssh-keygen Generating public/private rsa key pair. Enter file in which to save the key (C:\Users\Dell/.ssh/id_rsa): id_rsa_abc Enter passphrase (empty for no passphrase): Enter same passphrase again: Your identification has been saved in id_rsa_abc. Your public key has been saved in id_rsa_abc.pub. The key fingerprint is: SHA256:iI0B…2ga0 dell@DESKTOP-4VC… The key’s randomart image is: ±–[RSA 2048]----+ … |OOB*o… | ±—[SHA256]-----+

I tried copy/pasting it, with and without those ----BEGIN/END lines.

And it doesn’t work

It says “Key invalid type, we support ‘ssh-rsa’, ‘ssh-dss’, ‘ecdsa-sha2-nistp256’, ‘ecdsa-sha2-nistp384’, ‘ecdsa-sha2-nistp521’, or ‘ssh-ed25519’.”

I suppose in theory I could create a good password and set up a key myself more manually, but what’s going wrong?

I wonder if maybe i’m doing things a wrong way around e.g. maybe you’re meant to create the key on the remote machine… But I think i’m doing it the right way around… using keys created on the local machine and trying to add them to the remote machine… I think I have that right. But the digitalocean interface isn’t letting me add them.

(not sure what tag to use as I couldn’t see one for ssh)
