 How to use smartcards with OpenSSH?
 
 OpenSSH contains experimental support for authentication using
-Cyberflex smartcards and TODOS card readers. 
+Cyberflex smartcards and TODOS card readers, in addition to the cards
+with PKCS#15 structure supported by OpenSC. To enable this you
+need to:
 
-WARNING: Smartcard support is still in development. Keyfile formats, etc
-are still subject to change.
+Using libsectok:
 
-To enable this you need to:
+(1) enable sectok support in OpenSSH:
 
-(1) install sectok
+	$ ./configure --with-sectok
 
-	Sources are instructions are available from
-	http://www.citi.umich.edu/projects/smartcard/sectok.html
+(2) If you have used a previous version of ssh with your card, you
+    must remove the old applet and keys.
 
-(2) enable SMARTCARD support in OpenSSH:
-
-	$ ./configure --with-smartcard [options]
-
-	You can also specify a path to libsectok:
-
-	$ ./configure --with-smartcard=/path/to/libsectok [options]
+	$ 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:
+(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
 
-(4) load a RSA key to the card:
+	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.
 
-	please don't use your production RSA keys, since
-	with the current version of sectok/ssh-keygen
-	the private key file is still readable
+(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)

+	If you do this, anyone who has access to your card
+	can assume your identity.  This is not recommended.
