+When using Mozilla NSS, TLS_KEY specifies the name of a file that contains
+the password for the key for the certificate specified with TLS_CERT. The
+modutil command can be used to turn off password protection for the cert/key
+database. For example, if TLS_CACERTDIR specifes /home/scarter/.moznss as
+the location of the cert/key database, use modutil to change the password
+to the empty string:
+.nf
+ modutil -dbdir ~/.moznss -changepw 'NSS Certificate DB'
+.fi
+You must have the old password, if any. Ignore the WARNING about the running
+browser. Press 'Enter' for the new password.
