| + | ===== RSA vs ecdsa vs ed25519 ===== | ||
| + | |||
| + | We accept RSA, ecdsa and ed25519 keys. | ||
| + | In case you are wondering, **ed25519** appears to be the most robust algorithm, followed by ecdsa and then RSA. | ||
| + | |||
| + | Pick one. | ||

| - | * The long story short with this guide is that you will ideally need to generate the SSH keys on your computer first. | + | === Install termux from PlayStore or F-Droid === |
| + | |||
| + | Install openssh: | ||
| + | |||
| + | <code bash> | ||
| + | $ pkg install openssh | ||
| + | </code> | ||
| + | |||
| + | === Generate key pair === | ||
| + | |||
| + | <code bash> | ||
| + | $ ssh-keygen -t ed25519 | ||
| + | Generating public/private ed25519 key pair. | ||
| + | Enter file in which to save the key (/data/data/com.termux/files/home/.ssh/id_ed25519): [enter] or specify where you want to store both keys | ||
| + | Enter passphrase (empty for no passphrase): | ||
| + | Enter same passphrase again: | ||
| + | Your identification has been saved in /data/data/com.termux/files/home/.ssh/id_ed25519. | ||
| + | Your public key has been saved in /data/data/com.termux/files/home/.ssh/id_ed25519.pub | ||
| + | </code> | ||
| + | |||
| + | === Copy your public key to our server and login in using public key authentication method === | ||
| + | |||
| + | <code bash>$ ssh-copyid /data/data/com.termux/files/home/.ssh/id_ed25519.pub youruser@shell.ircnow.org</code> | ||
| + | <code bash>$ ssh -i /data/data/com.termux/files/home/.ssh/id_ed25519.pub youruser@shell.ircnow.org</code> | ||
| + | |||
| + | === Bookmark this connection === | ||
| + | |||
| + | <code bash> | ||
| + | $ vi /data/data/com.termux/files/home/.ssh/config | ||
| + | Host shell | ||
| + | HostName shell.ircnow.org | ||
| + | User youruser | ||
| + | Port 22 | ||
| + | IdentityFile /data/data/com.termux/files/home/.ssh/id_ed25519 | ||
| + | </code> | ||
| + | |||
| + | Congratulations. You may now login to our shell securely by simply running: | ||
| + | |||
| + | <code bash>$ ssh shell</code> | ||
| + | ==== UNIX-like OS (BSD, Linux, Minix, illumos, MacOS) ==== | ||
| + | |||
| + | === Generate key pair === | ||
| + | |||
| + | <code bash>$ ssh-keygen -t ed25519 | ||
| + | Generating public/private ed25519 key pair. | ||
| + | Enter file in which to save the key ($HOME/.ssh/ed25519): [enter] or specify where you want to store both keys | ||
| + | Enter passphrase (empty for no passphrase): | ||
| + | Enter same passphrase again: | ||
| + | Your identification has been saved in $HOME/.ssh/ed25519. | ||
| + | Your public key has been saved in $HOME/.ssh/.ssh/ed25519.</code> | ||
| + | |||
| + | === Copy your public key to our server and login in using public key authentication method === | ||
| + | |||
| + | <code bash>$ ssh-copyid $HOME/.ssh/ed25519.pub youruser@shell.ircnow.org</code> | ||
| + | <code bash>$ ssh -i $HOME/.ssh/ed25519.pub youruser@shell.ircnow.org</code> | ||
