NAME
ssh-add - adds RSA or DSA identities to the authentication agent
SYNOPSIS
ssh-add [-lLdD] [file ...]
ssh-add -s reader
ssh-add -e reader
DESCRIPTION
ssh-add adds RSA or DSA identities to the authentication agent,
ssh-agent(1). When run without arguments, it adds the file
$HOME/.ssh/identity. Alternative file names can be given on the command
line. If any file requires a passphrase, ssh-add asks for the passphrase
from the user. The passphrase is read from the user's tty. ssh-add re-
tries the last passphrase if multiple identity files are given.
The authentication agent must be running and must be an ancestor of the
current process for ssh-add to work.
The options are as follows:
-l Lists fingerprints of all identities currently represented by the
agent.
-L Lists public key parameters of all identities currently repre-
sented by the agent.
-d Instead of adding the identity, removes the identity from the
agent.
-D Deletes all identities from the agent.
-s reader
Add key in smartcard reader.
-e reader
Remove key in smartcard reader.
FILES
$HOME/.ssh/identity
Contains the protocol version 1 RSA authentication identity of
the user. This file should not be readable by anyone but the us-
er. Note that ssh-add ignores this file if it is accessible by
others. It is possible to specify a passphrase when generating
the key; that passphrase will be used to encrypt the private part
of this file. This is the default file added by ssh-add when no
other files have been specified.
$HOME/.ssh/id_dsa
Contains the protocol version 2 DSA authentication identity of
the user.
$HOME/.ssh/id_rsa
Contains the protocol version 2 RSA authentication identity of
the user.
ENVIRONMENT
DISPLAY and SSH_ASKPASS
If ssh-add needs a passphrase, it will read the passphrase from
the current terminal if it was run from a terminal. If ssh-add
does not have a terminal associated with it but DISPLAY and
SSH_ASKPASS are set, it will execute the program specified by
SSH_ASKPASS and open an X11 window to read the passphrase. This
is particularly useful when calling ssh-add from a .Xsession or
related script. (Note that on some machines it may be necessary
to redirect the input from /dev/null to make this work.)
AUTHORS
OpenSSH is a derivative of the original and free ssh 1.2.12 release by
Tatu Ylonen. Aaron Campbell, Bob Beck, Markus Friedl, Niels Provos, Theo
de Raadt and Dug Song removed many bugs, re-added newer features and cre-
ated OpenSSH. Markus Friedl contributed the support for SSH protocol
versions 1.5 and 2.0.
