+How to use NSS tokens with OpenSSH?
+
+This version of OpenSSH contains experimental support for authentication using
+keys stored in tokens stored in NSS database. This for example includes any
+PKCS#11 tokens which are installed in your NSS database.
+
+As the code is experimental and preliminary only SSH protocol 2 is supported.
+The NSS certificate and token databases are looked for in the ~/.ssh
+directory or in a directory specified by environment variable NSS_DB_PATH.
+
+Common operations:
+
+(1) tell the ssh client to use the NSS keys:
+
+ $ ssh -o 'UseNSS yes' otherhost
+
+ if you want to use a specific token:
+
+ $ ssh -o 'UseNSS yes' -o 'NSS Token My PKCS11 Token' otherhost
+
+(2) or tell the agent to use the NSS keys:
+
+ $ ssh-add -n
+
+ if you want to use a specific token:
+
+ $ ssh-add -n -T 'My PKCS11 Token'
+
+(3) extract the public key from token so it can be added to the
+server:
+
+ $ ssh-keygen -n
+
+ if you want to use a specific token and/or key:
+
+ $ ssh-keygen -n -D 'My PKCS11 Token' 'My Key ID'
