How do I generate a pair of SSH keys to be able to use in several apps (Juice SSH, Turbo, etc) to access my remote host? I've tried generating them with Connectbot, JuiceSSH and on a Linux machine, but none seem to work...

EDIT: I've generated the keys the way I usually do, with ssh-keygen -t rsa -b 4096, copied the private key to a ssh/ folder on my phone's internal memory (which I later point to in the client software) and added the public key to the .ssh/authorized_keys file on my server.

  • OK – then it looks good to me, and should work. I'm pretty sure I used RSA as well, and almost sure on the 4k. So I don't see where it should fail here. But thanks for filling the gaps – hopefully this enables someone else to spot a thing. – Izzy Mar 12 '15 at 12:43

You could install Termux, a terminal shell with additional Linux functionality on top of Android, with a package manager, so you can scale the magnitude of native Linux functionality at will. Then enter

pkg install openssh

Key-pairs in different formats will be generated upon OpenSSH install.

  1. Install Termux from Google Play Store
  2. Open Termux and execute pkg install openssh
  3. Installation scripts automatically generates four public/private key pairs at /data/data/com.termux/files/usr/etc/ssh/ folder for RSA, DSA, ECDSA, and ed25519 encryption algorithms.
  4. If you prefer to do it manually and setup a passphrase just execute ssh-keygen -t rsa -b 4096 and follow the process.
