 Keys are added using

 When executed without arguments,

 If the identity has a passphrase,  
 .Xr ssh-add 1  
 asks for the passphrase on the terminal if it has one or from a small X11  
 program if running under X11.  
 If neither of these is the case then the authentication will fail.  
 It then sends the identity to the agent.  
 Several identities can be stored in the  
 agent; the agent can automatically use any of these identities.  
 .Ic ssh-add -l  
 displays the identities currently held by the agent.
