Generate private key in iOS aRDP Pro app
Hi,
Thank you for the great software (aRDP Pro) that you have made. Our customers need to generate a private key on the device (for security reasons) and mail us the public key. In order to do so it would be great if there was a "generate private key" and "copy public key" buttons that generate and copy the ECDSA key. I hope you can add this to the iOS version (AFAIK the Android version already has such functionality). We tried copy-pasting the key, but people create wrong key types and also make mistakes with copy-pasting, leading to rejection of the SSH key.
Kind regards,
Joost and Maurits van der Schee
Hi @mevdschee this is a great feature request. In the meanwhile, as a workaround, a command like the following:
ssh-keygen -t ecdsa -f /tmp/keyfile1 -N ""
Will generate a key without a passphrase whose private part you can paste right into the application.
Ah, was just trying to figure out where the key generation was and came across this issue. Good workaround.
EDIT: Forgive my ignorance, but is ssh-keygen done from a terminal and not the device itself?
EDIT2: The SSH keys I am using are instantly failing every time ...
EDIT3: I don't really like that I had to fish through closed issues to figure out I shouldn't be using RSA keys but ECDSA keys instead. I did manage to get in, but no sound was passed through and it ended up being a lot more difficult to use than expected for an RDP client.
Hi @biggestsonicfan, thanks for your feedback. Yes, it looks like RSA keys are on the phase-out on newer OpenSSH versions, and you have to do workarounds server-side to re-enable them nowadays. This is no fault of the app.
Yes, it's admittedly inconvenient to generate keys off-app, and that's why this feature request is open. There is just me working on the app at the moment, and the alternative to an inconvenience would be not having the app available altogether which I felt was worse.
As far as no sound is concerned, what are you connecting to? If it's xrdp, there are challenges with sound from a quick look https://unix.stackexchange.com/questions/620849/xrdp-sound-redirection-ubuntu-20-04 for a link to a blog post as well as instructions to kill (and restart) pulseaudio daemon with -k.
You know you can refund the app on the App Store any time, right? https://support.apple.com/en-ca/118223

I did end up going the refund route and I think it's mainly the 5th gen iPad's fault. I thought it might finally get some use through RDP but it looks like it's too clunky to handle it.
https://gitlab.com/iiordanov/remote-desktop-clients-ios/-/commit/430b4cc6aa176b0b7d468a43f7a2784a18b9e30b provides functionality to generate an ssh key in-app.
Thank you very much! I'm looking forward to a much easier on-boarding of iOS users on our RDP over SSH service(s).
@mevdschee I need help Beta testing version 40 of aRDP that uses a newer library and is compiled for Mac Catalyst Silicon architecture. If you're interested in helping ensure the next version is stable and works for your use-case, please send an email to support at morpheusly dot com.
