Add Support for ed25519 Keys


We should support ed25519 keys. Right now if you try to add one via the UI it claims that the key is invalid.

Error: it looks like private key is invalid key. Double check If we can help, contact us.

This isn’t a bug per se, the key type is just not supported at this time. If you would like to see this feature please be sure to click on the heart below!

Unable to add an SSH key
Problems with ssh keys

Im also not able to SSH into containers with ed25519 keys.

It says the key is denied. An RSA key works just fine however.


Any word on this? SSH has supported ed25519 for a couple of years now. The version on Circle isn’t that old, is it? There must be something simple blocking this from working.
