.Sh DESCRIPTION
.Nm
-is a program to hold authentication private keys.
+is a program to hold private keys used for public key authentication
+(RSA, DSA).
The idea is that
.Nm
is started in the beginning of an X-session or a login session, and
all other windows or programs are started as clients to the ssh-agent
program.
Through use of environment variables the agent can be located
-and automatically used for RSA authentication when logging in to other
+and automatically used for authentication when logging in to other
machines using
.Xr ssh 1 .

but is normally added to the agent using
.Xr ssh-add 1
at login time.
-.It Pa /tmp/ssh-XXXX/agent.<pid> ,
+.It Pa $HOME/.ssh/id_dsa
+Contains the DSA authentication identity of the user.
+.It Pa /tmp/ssh-XXXXXXXX/agent.<pid>
Unix-domain sockets used to contain the connection to the
authentication agent.
These sockets should only be readable by the owner.
The sockets should get automatically removed when the agent exits.
