 * 			"https-server1-"
 * keyPrefix - prefix added to the beginning of the key database example: "
 * 			"https-server1-"
 * secmodName - name of the security module database (usually "secmod.db").
 * flags - change the open options of NSS_Initialize as follows:
 * 	NSS_INIT_READONLY - Open the databases read only.
 * 	NSS_INIT_NOCERTDB - Don't open the cert DB and key DB's, just 
 * 			initialize the volatile certdb.
 * 	NSS_INIT_NOMODDB  - Don't open the security module DB, just 
 *			initialize the 	PKCS #11 module.
 *      NSS_INIT_FORCEOPEN - Continue to force initializations even if the 
 * 			databases cannot be opened.
 *      NSS_INIT_NOROOTINIT - Don't try to look for the root certs module
 *			automatically.
 *      NSS_INIT_OPTIMIZESPACE - Use smaller tables and caches.
 *
 * Also NOTE: This is not the recommended method for initializing NSS. 
 * The prefered method is NSS_init().
