How to use smartcards with OpenSSH?
|
||||
|
||||
OpenSSH contains experimental support for authentication using
|
||||
Cyberflex smartcards and TODOS card readers, in addition to the cards
|
||||
with PKCS#15 structure supported by OpenSC. To enable this you
|
||||
need to:
|
||||
|
||||
Using libsectok:
|
||||
|
||||
(1) enable sectok support in OpenSSH:
|
||||
|
||||
$ ./configure --with-sectok
|
||||
|
||||
(2) If you have used a previous version of ssh with your card, you
|
||||
must remove the old applet and keys.
|
||||
|
||||
$ sectok
|
||||
sectok> login -d
|
||||
sectok> junload Ssh.bin
|
||||
sectok> delete 0012
|
||||
sectok> delete sh
|
||||
sectok> quit
|
||||
|
||||
(3) load the Java Cardlet to the Cyberflex card and set card passphrase:
|
||||
|
||||
$ sectok
|
||||
sectok> login -d
|
||||
sectok> jload /usr/libdata/ssh/Ssh.bin
|
||||
sectok> setpass
|
||||
Enter new AUT0 passphrase:
|
||||
Re-enter passphrase:
|
||||
sectok> quit
|
||||
|
||||
Do not forget the passphrase. There is no way to
|
||||
recover if you do.
|
||||
|
||||
IMPORTANT WARNING: If you attempt to login with the
|
||||
wrong passphrase three times in a row, you will
|
||||
destroy your card.
|
||||
|
||||
(4) load a RSA key to the card:
|
||||
|
||||
$ ssh-keygen -f /path/to/rsakey -U 1
|
||||
(where 1 is the reader number, you can also try 0)
|
||||
|
||||
In spite of the name, this does not generate a key.
|
||||
It just loads an already existing key on to the card.
|
||||
|
||||
(5) Optional: If you don't want to use a card passphrase, change the
|
||||
acl on the private key file:
|
||||
|
||||
$ sectok
|
||||
sectok> login -d
|
||||
sectok> acl 0012 world: w
|
||||
world: w
|
||||
AUT0: w inval
|
||||
sectok> quit
|
||||
|
||||
If you do this, anyone who has access to your card
|
||||
can assume your identity. This is not recommended.
|
||||
|
||||
|
||||
Using OpenSC:
|
||||
|
||||
(1) install OpenSC:
|
||||
|
||||
Sources and instructions are available from
|
||||
http://www.opensc.org/
|
||||
|
||||
(2) enable OpenSC support in OpenSSH:
|
||||
|
||||
$ ./configure --with-opensc[=/path/to/opensc] [options]
|
||||
|
||||
(3) load a RSA key to the card:
|
||||
|
||||
Not supported yet.
|
||||
|
||||
|
||||
Common operations:
|
||||
|
||||
(1) tell the ssh client to use the card reader:
|
||||
|
||||
$ ssh -I 1 otherhost
|
||||
|
||||
(2) or tell the agent (don't forget to restart) to use the smartcard:
|
||||
|
||||
$ ssh-add -s 1
|
||||
