@barchard ed25519 is supported in general but the cipher 1Password uses for encrypting private keys is not so you need to use ssh-keygen on 1Password keys to get them into Secure ShellFish.
@ShellFish is there any guides on this? Can ShellFish generate a ed25519 key instead of RSA? I’m having trouble using SSH keys but the one generated via 1P worked fine. Thanks.
