<P>SSH keys are typically stored in <CODE>$HOME/.ssh</CODE>.</P>
|
|
<P>Typically, the public key's filename will be suffixed with <CODE>.pub</CODE>, while the private key will not.</P>
|
|
<P>You can generate an SSH key with <CODE>ssh-keygen(1)</CODE>. Currently the preferred implementation is <CODE>openssh-keygen</CODE>, part of the OpenSSH suite.</P>
|
|
<P>
|
|
Microsoft GitHub documentation suggests a user create a key with <CODE>ssh-keygen -t ed25519 -C "[<I>e-mail address</I>]"</CODE>.
|
|
This generates an <A HREF="https://en.wikipedia.org/wiki/EdDSA#Ed25519">Ed25519</A> SSH key with an e-mail address in the key comment.
