Test Cases

Testing out system NSS.

Part 1: enabling system NSS

In Fedora 12, system NSS is available, but not enabled. The following steps will enable system NSS.

1) As root run

certutil -K -X -d sql:/etc/pki/nssdb (this will create sql db's from the local dbm database).

2) as root edit /etc/pki/nssdb/pkcs11.txt

 2a) stanza with NSS Internal PKCS #11 Module, change:
 2b) in the same stanza, on the NSS= change the Flags from:
 2c) save your changes (Note, there should be no spaces in the library= line, nor any spaces between the flags.

3) as yourself, in your .bashrc or .cshrc (or whatever shell you use) add:

   export NSS_DEFAULT_DB_TYPE=sql
  [ of cource for csh/tcsh that sould be setenv 'NSS_DEFAULT_DB_TYPE sql' ]

4) as yourself (not as root!!!) 'certutil -N -d sql:/etc/pki/nssdb'. If you supply a password, this password will eventually become your new firefox/thunderbird master password.

Part 2: convince Firefox, Seamonkey, Xulrunner and Thunderbird to use system NSS. Firefox and Thunderbird still use private directories to store their NSS databases. It's possible, however, to convince them to open system NSS. All these steps should be performed as a user. In the future these applications would handle these steps by themselves automatically.

Do each of the following steps in each of the profile directories for which you wish to use system NSS in. Firefox, thunderbird, and seamonkey each have their own directories and can have multiple profiles (if you don't know what a profile is, you probably only have one per application). You can the base of the profile directories for firefox at ~/.mozilla/firefox and thunderbird at ~/.thunderbird. In that base directory there is a file called 'profiles.ini' which lists all the profiles that are known for that application. For each profile there's a line called 'Path=' which points to the actual profile directory. Usually it's a subdirectory under the current directory and has a random 'salted' name like 'quxz7me5.default'. do the following instructions while cd'd to that directory:

1) certutil -K -X -d sql:.

  (if you have a master password set, You'll have to provide it here). This will create a new sql database from your old dbm database.

2) certutil --merge -d sql:~/.pki/nssdb --source-dir sql:.

  (if you have a password set on sql:~/.pki/nssdb (from step 4 above), You'll have to provide it here. If that password is different from the master password for the profile, you'll also have to supply the profile password. If ~/.pki/nssdb has to password, but the profile database does, ~/.pki/nssdb will inherit that password (which you will then need on future instances of this step). If you want to change that password use 'certutil -N -d sql:~/.pki/nssdb'. Supplying an empty password will remove any password.

2) edit pkcs11.txt

  2a) in the 'NSS Internal PKCS #11 Module' stanza. change:
   parameters=configdir='/home/{you}/.mozilla/firefox/quxy6me8.default' ..... Flags=internal,critical
   parameters="configdir='sql:/etc/pki/nssdb' ..... Flags=internal,critical,moduleDBOnly"
  NOTE: the ... represents a very long string of parameters that should remain the same. Note the addition of the double quotes around the parameters. This tells NSS to use the parameters as given and now rebuild them based on application input.
  2b) save pkcs11.txt

3) Make sure you set NSS_DEFAULT_DB_TYPE to sql in your environment before you start FF or TB

Restoring your system to the old databases: Simply unset the NSS_DEFAULT_DB_TYPE variable and all your applications will fall back to their former dbm style database

Test 2: Testing out enablement FIPS mode. Note: We actually testing nss-softokn here.

You can enable FIPS mode in Firefox, Thunderbird, or durectly using modutil.

Test 2a: Enable FIPS mode in Firefox
 2a-1 - Launch Firefox
 2a-2 - Open the menu Edit->Preferences
 2a-3 - In the Security tab click on the "Use Saved Password
 2a-2 - Open the menu Edit->Preferences
 2a-3 - In the Encrypton tab click on the "Security Devices" button
 2a-4 - When the Device Manager window show up click on the "Enable FIPS" button
 2a-5 - Click OK
 This operation should succeed
 2a-6 - Click Close
 2a-6 - Shutdown and relaunch Firefox
 2a-7 - You will be prompted for a password
 That password prompt indicates that fips mode has been turned on

Test 2b: Enable FIPS mode in Thunderbird

 The steps for Firefox apply to Thunderbird

Test 2c: Enable FIPS mode via the nss command line tools

 2c-1: In a convenient place create a brand new database
       rm -rf /tmp/nssdb4testing
       mkdir -p /tmp/nssdb4testing
       certutil -d sql:/tmp/nssdb4testing -N
       Enter a password when prompted (optional)
 2c-2: Turn FIPS mode on: modutil -dbdir sql:tmp/nssdb4testing -fips true -force
       Enter the password when prompted
       It should display FIPS mode enabled.
 2c-3: Double-check: modutil -dbdir sql:tmp/nssdb4testing -chkfips true
       It should display FIPS mode enabled
 2c-4: Disable FIPS: modutil -dbdir sql:/tmp/nssdb4testing -fips false -force
       There should be no promp and it sould display: FIPS mode disabled.

In the steps above we explicitly used the "sql:" prefix to ensure that an sqlite-based shared database is used. Repeat the steps above using the "dbm:" prefix to test the legacy database.

Test Results

Construct a table or list to allow testers to post results. Each column should be a test case or configuration, and each row should consist of test results. For example:

User Smolt Profile Sample test 1 Sample test 2 Sample test 3 Sample test 4 References
