According to RFC 4648 base64 padding is depend on input length and SSH key fingerprint length always need one = padding character.. As It's not required by base64 spec so ssh-keygen, Golang and AWS may treat this padding differently but in the end it's identical so I think it's safe to trim those padding character out before comparing or switch to another comparing function that aware this .

Both AWS and eksctl use the same algorithm to generate the fingerprint for Ed25519 keys, but the Go implementation uses an unpadded base64 encoding (base64.RawStdEncoding), which is why the eksctl-generated fingerprint has no padding (=). Sorry, for now, please try using a different keytype. But for the sake of trying. :) I was going mad about this. Well, for a first take, I'd look at the file timestamps ( /etc/ssh/ssh_host* ), though those are not a reliable means of knowing when a file was changed.
